The era of metal in Dong Nai - Part IV

​    Early iron phases ( the second half of Millenium I B.C )

     This is the highest stage of development of systems complex cultural history of Dong Nai , with the achievement of economic exchanges - new cultural and technological advancements related to advanced technology invention and application of wrought iron products of the industry in production practices - fighting tradition, starting from the middle of TNK I tr.CN. In the area of ​​Dong Nai province , typical monuments of historical periods centered around this vibrant red area Basalt Xuan Loc - Long Khanh ancient , where " the world of the volcanic cones " Pleistocene period . It is considered that this is the generation and colony important and most constant of the ancient Dong Nai , the dynamics of cultural traditions - the technical metal is also one economic area residents crystal center spirit at a time when the primitive community of Dong Nai constructor civilized life with the power structure brings comedy primitive state of their own . A specific type of relics of the early Iron in Dong Nai is the ancient agricultural village studio professional craft of bronze casting - wrought iron - Patent and wholesale jewelry with precious stones - agate - glass gold or silver ... and , inside the ancient cemetery next to the residence , was formed on the slopes of a small hill of red soil along streams separate cemeteries to bury the dead in coffins ceramic jars you .

     Monuments located on a hillside stream fox sepia Basalt western coastal streams Hap , hamlet of Vinh Bao B , Binh Xuan ( Xuan Loc ) , 4 km from Xuan Loc and vestige Iron Bridge - Mit Hill - Mango Hill only 3 - 5 km to the northeast . Monuments by Earl Deng findings from 1976 , then , Dong Nai Museum staff , KCH Center , LSVN Museum , Institute of KCH , and Japanese archaeologists have repeatedly reconnaissance survey ( 4 m2 ) and 2 times the excavation ( 4-1978 and 4-1979 ) with 3 pit area = 133 m2 . Vestiges of ancient culture in the stream extends for 40,000 m2 Weasel . Scientists have discovered an ancient residence with living material layer thickness from 0.3 to 1.4 m and 1 separate graveyard for burial jar 9 ceramic shell containing grave goods inside . Relics and tombs where the collected material including the collection of domestic and imported products rich . Stone : 1 hoe , ax 80 four- , chisel 5 , 14 goals grinding tools or jewelry rings , 6 knives harvesters , 1 pestle grinding , 1 amulet worn , 10 mold casting sandstone used axes, spears, awls , earrings , rattles or small bell , 13 piece bracelet , 2 earring beads and more . Earthenware have 14 teams will fiber , 2 rounds , 2 weights with your chum coffins 9 and 8 pancreas . Glassware : 1 2 bracelets and earrings have 3 green. Supplies metals : copper ax 5 , 5 for iron , 1 iron sickles and 1 spade ( 1 bronze ax sample chemical analysis - Institute of Geological spectrum in Hanoi, said alloy composition is : Cu + Pb + Sn ) . Monuments fox stream , including monuments and tombs residence , determined equivalent to the " Plain of Jars " Phu Hoa - Dau Giay - Suoi Da , about half after TNK I tr.CN. However, the stream selected from the ancient village sites to reside in the same burial structures like strata should be understood as the time constant , is endogenous in the structural material culture , but in many areas the coastal areas in the hills this spring Hap , traces of the traditional tomb with burial ground ax copper products still exist in dimension and appearance of grave overwhelms you and the type of materials modern jewelry ( gemstones, onyx , glass color ) like the unusual pigment composition join and cultural identity documents using the early Iron Dong Nai .

     Di only carry name Dau small stream adjacent Unified District 2 - Xuan Loc , TP way . HCM is about 70 km to the east - northeast , by E. Saurin detected 10-1965 . This is the ancient village including residences with thin cultural layer ( 10-20 cm ) and soil laterite hills . Here , E. Saurin not detect 2 burial jar lid , inside the bones contain 1 , 1 piece of table ware, 1 broken quartz and ceramics of vases, pots and little charcoal. Relics collection includes : 2 iron knife blade with 2 sharp edge , 1 piece of stripped stone , crushed 1 Baseball , 1 roller , 1 stone carving and grinding grooves table , have a special ax 3 piece casting molds , earring and the needle . Broken pottery made ​​here sandy clay , coal or crop residues burned to ashes and shredded many minerals such as mica , quarto - felspathique ... , firing high , shaped and decorated quite nice . It is the mouth piece of the pot bottom flared curved , flared necked bottle or shoulder , slightly concave disc with a flat bottom , vials , jars belly hatch ... with rope decoration , incised create closed circles , waves , tablature , wolf teeth , wavy or spiral ... Dau relics have contained material stratigraphy and artifacts collection worth clarifying cultural structures of post- contract stage - Dong Nai and the early iron along with the remains - Spring burial networking options the cultural characteristics of the final development stage of social history - Dong Nai primary use .

    Phu Hoa ( 10053'45 '' N - 107015'00 '' E ) is the old name of one hamlet , where the casket cemetery occupies the ancient pottery jars 1 red dirt hill 200 m high Basalt / sea level , looking down narrow valley surrounded by two branches of the river Ray , located in Baoding village ( Xuan Loc ) , along the way , Highway and Xuan Loc 3 km to the south . Monuments by local people discovered 3-1971 , and Hoang Thi Body H.Fontaine survey and excavation , " Fire " , 46 burial jar handle . After 1975 , Hoang Thi Than the Dong Nai Museum staff , KCH Center has recent revision and then from 1977 to 1979 , the Vietnam BTLS Institute , University of Hanoi synthetic investigation , detectives dug several holes 1 more closely and discovered your small badges with 1 stone , ceramic fragments of various jars .

    According to the announcement of H.Fontaine (1971 - 1975) , the high beam is about 75 cm wide with abdominal 40-80 cm , irregular arrangement , sometimes in clusters , sometimes intermittent leave , but are buried stands at different depths . Jars made ​​from larger particles of sand and clay mineralogy ( quarto - felspathique ) , smooth strokes red pink shirt , some decorated with spiral bands forming the letters S or serial lying equidistant . Supplies are extremely rich grave , but the ancients were not arranged in the jars , usually jewelry of all kinds, household wares and tools - tools and weapons of iron . Statistical overview map of Phu Hoa burial artifacts to shape 1973 , in which there is an Iron Age : 9 hoes , 2 axes , knives 5 ​​, 13 sickles , 11 for the 2 edges , 1 weights . In addition to 46 coffins jars , ceramic containers : 7 round-bottomed pot decorated ice wolf tooth transverse abdominal , 14 per necking round or egg-shaped design , with the bottom plate 46 or bends in the 2 hole rim to tie slings , 4 cups , 5 rounds or flats , in addition to a regular vertical spool with holes , like Sa Huynh light foot , heel catcher ... with patterned types such imprinted decorative fabric , put a strip , smooth strokes and incised geometric blueprints to create curves , short brick , wolf teeth , put a little oblique , rectangular , wave or S connected together ... Phu Hoa Jewellery diverse and include : 1 silver necklaces , 22 bracelets ( 4 grinding stone shiny , dark green glass ring 2 , 15 double rings with 1 round left marks on the fabric smooth round , 19 iron ring made ​​of two round steel bars stuck together , 5 iron ring , 8 nephrite jade earrings white veined with 2 earrings shaped gargoyle 2 and 6 3 earrings jewelry line like that aboriginal domain Philippine mountain called " Lingling - O " , 2 rattles and beads chain co ... County accounted for 1,800 specimens , of which , apart from one grain of gold , the other of two groups : particles with a diameter of 200 over 0 , 5 cm ( 30 % spherical , cylindrical round 30 % , 20 % fusiform , 1 grain of stations , and the rest is long pearl with 6-7 exposed area ) ; kind of diameter less than 0.5 cm glass is often artificially colored red, green , orange , yellow , green , or precious stones like agate , garnet , cornaline ... ) .

    According H.Fontaine and Hoang Thi Than, Phu Hoa relics , along with 9 Dau Giay and Hang Gon derived from the Sa Huynh culture in the south central coast of Vietnam, with the results of her assessment C14 G. Delbrias at Centre des Fablo Radioactivites in Gif - sur - Yvette ( France ) 1 piece of pottery jars M8 and charcoal samples in the jars M11 , M13 is 2400 ± 140 and 2590 ± 240 years ago .

     Hang Gon 9 Monuments located on a hillside piece of red soil along streams whether Basalt ( also called streams ) , an area of ​​about 100 x 50 m = 5000 m2, E. Saurin discovered in 1963 , located in Rubber Plantation Hang Gon Xuan Tan ( now part of Long Khanh district ) , the town of Xuan Loc, 10 miles southwest . For the first time in this survey , E. Saurin found only 2 ceramic jars have surrendered the 2 earrings , 1 for iron and broken pottery . Then he discovered another 60 buried jars stand at a depth of 0.2 to 1.5 m with different lids . In chum not see dead tooth and bone ashes , just the normal things the old burial deliberately smashed or broken before burial . Outside burial jar , sometimes they were buried together with many pots , iron or stone axes intact .

     Chum coffins often high 40-60 cm to about 40 cm wide and mouth burial containing products include : 2 stone axes , one for iron , 1 iron hoes , 3 axes iron throat and tongue rolled flat -panel inspection ( chemical composition iron studies were E. Saurin assessment indicates that besides iron are major elements , and all traces of chrome , nickel , copper , maganene , molybdene , lithium ) . Pottery types : fiber frustum team will be decorated with wolf teeth around the edges , folded tubular ceramics , candlesticks , decorative lids concentric circles on the disk eager , wide mouth cup text-decoration style waves or tablature or the slash on the rim edge , bottle with different types : folded edges trimmed in brushed sparse literature ; edge of the curved wide , thin edge claws small side valley bottoms , wide mouth bottom by ... Decorative motifs characteristic of ceramic Hang Gon is the spiral between the narrow band . Jewellery includes : 1 gold beads rolled flat pyramid has 2 sections bend do wear line ; County cornaline chain with red polygon , with tubular agate round bulging slightly , by pagodite white , with zircon golden brown with a regular hole wire , blue glass disc -shaped cushion multiple edges , slightly opaque orange-red tubular ; 1 gold plated earrings , earrings 2 1 stone gargoyle pagodite ...

Hang Gon 9 relics have 2 samples of wood charcoal DJ Center Thomaret expertise in Monaco and one scientific specimens by Mrs. G. Delibrias analyst at the Center for weak radiation at Gif - sur - Yvette , for C14 dating results : 2300 , 2190 , 2100 ± 150 years ago . Even in the coffin that 's not reinforced ceramic or coal ash , E. Saurin still think this is the cremation burial jar like custom Indonesien general population . He said that the owner of this monument has ties to continue using ceramic coffin in Phu Khuong ( Quang Ngai ) or Dau , Phu Hoa ( Dong Nai ) and can continue relations with burial in the " Klong " of Cham , own jewelry jars buried in the tomb of foreign origin imported from many major centers of world civilization . This cemetery dating Author equivalent to the Dong Son culture , beginning about 500 years tr.CN and ends in the first century after AD. In our opinion , cemetery monuments chum Hang Gon 9 , along with Spring Weasel - Dau Giay - Phu Hoa and the burial jar sites Gio showed diffuse and strong acculturation between Sa Huynh culture and traditional era metal - iron age cultures Dong Nai and forming a vestige carry full cultural nature of the final stages of development in the early history of Dong Nai and the entire address of the system downstream this river system .

    Besides vestige Spring burial jar you select - Dau Giay - Suoi Da - Phu Hoa and agricultural villages - Iron craft the early period , in the red area Basalt Xuan Loc - Long Khanh also present the relics material culture - the spirit of Dong Nai different characteristics : architectural relics tombstone large ( megalithic ) Hang Gon or warehouses contain large amounts of weapons - tools - rare animal statues on top of the mountain Giao Long neck fire .

     Hang Gon megalithic tomb formerly of rubber plantations Xuan Loc , Xuan Loc , Lam normal overall , Bien Hoa province , later renamed Hang Gon village , Giao Thoi commune , Xuan Loc District , Long Khanh and Xuan hamlet Thanh , Tan Xuan , Xuan Loc , Dong Nai province , today it is hamlet Hang Gon Xuan Thanh , Long Khanh district . Monuments megalithic tomb known as Xuan Loc , is first E. Saurin No. 7 in the 10 monuments that he studies in this plantation ( Hang Gon 7 ) , while local people built a small temple worship , " Mr. Stone " also carries the nickname " he " . Tomb of the huge rocks on the red hills Basalt , altitude 256 m above sea level , where the most recent excoriation from 800-900 m , by Provincial Highway 2 about 100 m to the west , the 8 km south of Xuan Loc Bien Hoa from Vietnam and 50 km to the east .

      In early 1927, when the provincial road No. 2 opening , road engineers J. French 1 Bouchot see rock jutting straight from under a large banyan tree , and from mid- April of that year , he excavated the area and notified 3 times from 1927 to 1929 . Findings of the " megalithic " here immediately attracted the attention of many Western scholars , starting from the archaeological owners Indochina H. Parmentier to L. Malleret , E. Gaspardone , H. Loofs , E. Saurin , H. Fontaine ... until recently with a visit to the understanding of archaeologists Russia, Germany , Bulgaria , Japan , USA .... Every ancient tombs were Gon ranking French government in 1930 , scoring 38 on the list of " Grave Indochina - monuments in the South ." From 1981 - 1982 , Dong Nai Museum and the Centre has repeatedly KCH investigation , research plans to recover relics protection . In 1984, Hang Gon dolmens are the Ministry of Culture - Information rankings . In early 1992, Dong Nai Museum , the Center organized excavations KCH 2 times to save themselves from the vaults subsidence and collapse , tectonic studies around the tomb and monument restoration ( Figure 9 ) . Earlier 12-1995 , while leveling conducted within the enterprise release of quarrying ( Rubber Plantation Hang Gon ) , who drove the bulldozer knocked cloth to 3 horizontal Granite from the tomb ancient rocks 60 meters southeast . Mr. Tran Tu Oai report issued Dong Nai Museum . After three emergency surveys , PPC permission of the Ministry of Culture and Information , Dong Nai Museum , excavated Center KCH " fire " from September 1-1996 . Megalithic monuments recently discovered organic contact with Hang Gon grave monument discovered in 1927 was ranked the national level . Every mission name Gon 7B for this megalithic architecture .

      Hang Gon 7A ( 10051'44 '' N - 107014'07 '' E ) . As announced by J. Bouchot and H. Parmentier , megalithic tombs rectangular shaped , assembled by 6 cloth with large granite lies west to east , between 4 pillars are: cylindrical sandstone 8 or higher to 2.5 Basalt - 3 m with carved concave saddle-shaped head , 2 head rest 2 cloth is large ( 7.2 x 1.1 x 0.35 m ) . The first excavations note 1 of extraction of raw materials like marble tomb as outcrops near Hang Gon Da Lat and visualize the extraordinary efforts of the past if they carry rocks when approached 10 ton travel hundreds of kilometers in the primitive conditions of the terrain is rugged brought up graves here . According to H. Parmentier , who initially submerged ancient construction in underground catacombs , the columns are buried around the trapezoidal step lower from the grave , support for effective tools to open and close the lid on the tomb which weighs nearly 7 tons . The raising and lowering the lid can tunnel thanks to the help of a pulley system at the pillar - mounting on hollow tree saddle and ligaments of the head portion protruding threaded through the open hatch and pull files can , according to the authors performed only open tomb in the burial ritual occasions have great community .

     Excavations 2nd with a total planned area of ​​over 1,400 m2 ( 44 x 32 m ) , is made according to the type of training steps to combat erosion . The highlights from the training center is : Stone Basement 1.7 m high , 4.43 m long and wide from 1.65 to 1.9 m ; cover large crypt ( 5.25 x 2.25 x 0 , 29 m ) . In addition, the findings also add 2 horizontal stone vaults , never to be J. Bouchot and H. Parmentier describes : 1 South adjacent wall crypts , roundish shape ( d = 1.3 m ) , near the northwest corner piece ( size 1.5 x 1.05 m ) was assembled in Figure 2 right angle grooves like identical to the first corner burial cloth background . The presence of broken pieces of stone bearing marks the 2nd floor of the possibility that even more quarries in the area , or at least the possibility that old pair crafted and fitted spot catacombs , can 1 panel that 's been removed money while performing .

      Hang Gon megalithic tomb , with sealed box shape is deep in the ground along with offices around the world and foreign scientists admit that the ancient architecture " unprecedented " in Vietnam . Of course , while recognizing the uniqueness of the architecture in many ways , from extraction , transportation and gathering megalithic materials , processing techniques - fitting pair - ... operation , relics see the marvelous achievements of ancient peoples in Xuan Loc - Dong Nai , scientists from more than 60 years is still very different perspectives on the origins and chronology of the monument .

      The first excavation , J. Bouchot (1927 - 1929) said that the relics related to Gia Rai ethnic groups living in the Central Highlands , but to compare the structure and size of the crypt columns around with many megalithic buildings in Asia ( North China , northern Burma , Assam , Transjordanie Deckker peninsula , Changkat Mentri ( Sungkai , South Perak , Malaysia ) or Java ) and conjectured that : Catacombs with 2 rows of marble pillars of the stone can new , sandstone column stocking up just in time to decorate Bronze more . H. Parmentier to think of the large stone building in Australia and Oceania , and architectural monuments of stone rectangles in East Prussia near Sa Huynh and Cham in Ninh Thuan grave number . According to L. Malleret (1963 ) , Hang Gon dolmens likely be built in the Bronze and influenced by Indian architecture in the works Tissamaharama and Anuradhapura in Sri Lanka with the semi-circular grooves at the top of the stone column . E. Saurin when relics are named Hang Gon 7 1968, to compare with the temple dating back 500-200 years tr.CN in North India , with stonework architecture " K " in the culture of Oc Eo in the Mekong Delta and the sites of the metal clusters due to his discoveries in the plantation sector Hang Gon , especially chum cemetery excoriation . P. Bellwood (1978 ) argue that the dolmens Hang Dong Pho Saigon 7 and are likely related to the Sa Huynh culture , we do not have uniformity in mainland Southeast Asia , except for a small group in the Malacca peninsula .

     For scientific Vietnam , while indirectly support the idea of H. Parmentier for this is collective tombs of many of the ancient warrior or that lid only allowed to move each large burial , have confirmed the grave stone built ingenious feats are not for ordinary people , but to services for the " great psychological crazy " history . Others agree with the views of L. Malleret , based on the words of a journalist after each training entries J.Bouchot click the small ceramic bowls that contain coal ash in catacombs that further conjecture cremation is done here . Then there are others interested in information of L. Malleret about 1 ring weighing 1,065 kg ( MBBN.3143 - BTSG ) by M. Parme picked up near dolmens and 1 brass bowl seems to leave traces on the ground in front of the tomb as told by the people participating in the grave , or thinking of E. Saurin when you contact technical graft large stones with grooves - dreams - key to the architecture " K " from Oc Eo carpentry ... These people recognize that employers megalithic tomb not belonging Hang Gon 7 or earlier the same time , which could be co- owner of the architectural monuments stones - large stones of Oc Eo culture in kind distribution along the central monument Dong Nai River " dating from the first century to the seventh century AD " .

     Hang Gon 7B ( 10051'43 '' N - 107014'10 '' E ) . In primitive rocks red brown spongy texture , very little laterite gravel , coal ash accumulation in places , excavations size 6.4 x 14 m = 89.6 m2 ; pillars , slabs located along elevation , just above the cap rock tomb Hang Gon 7A approximately 0.5 m , coordinator of 3 clusters : two clusters of 2 plane rectangular stones arranged west to east , size : 5.1 x 1 , 6 to 1.75 x 0.05 to 0.1 m and 2.6 x 1.15 x 0.12 m, with 1 to 2 bar phrase pillar length from 3.25 to 3.4 x 0.2-0 , 3 m horizontal inputs bunched together and 1 large oval stone cobbles . All pillars , slabs are processed traces ( opaque , trimmed , cut grooving grinding jaws , tight corners or trim the edges ... ) . Under the granite slabs , archaeologists discovered many artifacts . It is 2 pieces of copper , can lid or rim of the tower or small bowl ( not to mention one piece of cutting tool to detect areas 45 m from the pit to the west . Both 3 samples were analyzed at the same chemistry - spectrum geological Institute said a key component alloy is Cu + Sn , Pb concentrations less , there is very little Zn ) . There are 24 pieces of pottery , including 6 oral , 16 relatives , 2 sockets , the hard ceramic turntable made ​​of coarse , sandy firing a low shot . Waste rock : 4413 specimens , of which 299 pieces of white marble and gray is the process of scrap processing office , recently discovered stone panels . ( Particularly the last piece 4114 with and without coating patine lies deepest in stratigraphic Hang Gon 7B . This may be the product of stonemasons Hang Gon after fabrication process outsourcing conglomerate primitive , long before their descendants to processing granite slabs and large stone pillars ) .

      Hang Gon Monuments 7B is the process in place since ancient granite and Diabaz ( ? ) Original slab blocks , with materials and techniques similar procedure has been known through the stages of creating the puzzle fitting parts the crypt [ format " Dolmen " ] . We contribute new material for the study of the structure of the whole population of a large rock at Hang Gon . On the basis of the arrangement of a recorded consciously woven plates and pillars ( the direction and elevation , the coordination and the burning ruins baked strata , can not exclude the possibility that ancient people produced , Rendering spot this megalithic monuments ) . The monument direct physical contact with megalithic monuments in bronze and pottery here is the neck . Basically , the composition of the alloy brass artifacts Hang Gon very close to production tools - Southeast weapon ever discovered and analyzed in Iron Bridge , vertical , Cu Lao Pho , spring Weasel and Long Transportation . Comprised of Gon has similarities with pottery Rock Stream , Stream Weasel , Ban Phu Hoa and Bac . However, the assessment results indicating the spectrum of the source materials indigenous to the particular chemical composition , unlike ceramic Silver abdominal muscles , Gio , The Mausoleum , Long Buu , including the prehistoric pottery Xuan Loc - Long Khanh as Iron Bridge , Mount Ceramic and excoriation .

These pieces of ancient pottery and copper and stratigraphy with granite scraps are justifiable evidence proving the age of formation of the megalithic constructions and nature contribute to interpretation of archaeological ruins the whole . We only made ​​the starting point for the construction of megalithic at Hang Gon between TNK I tr.CN and megalithic relics have complete structure including dolmen and built works , not stop using the supplement and lasted until the early centuries schedule . From 4 C14 analytical results in nuclear City Centre . HCM spreading from : 2720 , 2590 , 2570 ± 50 and 2220 ± 55 years ago . We can imagine the beginning of a historic peak periods of prehistoric cultural complexes - full profile used in the southeastern Vietnam - At the stage of post-production - the early Iron . With the convergence center relocation - promoting mining activities in many diverse ecological zones is agriculture - manual labor - develop trade and economic exchanges - cultural - technical level areas of community residents and long -term survival designing and building of this rich natural region in the past. Past history of demand and efforts at extraordinary intellect to assert itself , with both space and time .

    To build large structures Hang Gon megalithic form requires computer prerequisite conditions that creativity - financial institutions , community empowerment is key incubating inside a primitive society has growth in stature of the times necessary and sufficient metal . The composition of " inert liver and minnows moon " stone works where large populations Hang Gon , Long Giao kind treasures and the " Plain of Jars " in the broad outlines of this region revealed partial face esprit Center deer during the primitive egg -style State South (Vietnam ) of the East and the continent.

      Long ancient treasure Communications ( 10049'27 '' N - 107046'06 '' E ) lies megalithic tomb Hang Gon than 4 km from the town of Xuan Loc and 20 km to the southeast . The site is located in the ancient soil slopes volcanic cones red Basalt ( Hill 57 ) located in Saigon Rubber Plantation Goods , by Mr. Tran Van XY discovered in 1982 . Part of artifacts collected at a depth of 0.2 m was later workers in Dong Nai Museum Center KCH recall include: 16 weapons known as " Over " ( Ko ) , 12 fragments of Directors and tongue through . In 5-1984 , when Chau Thanh investigation , they find more 3 blade wander through here . Until the early 90s , Traditional room Rubber Plantation Cam receives many relics dug by the farm staff at Long Giao . The most interesting are : 2 over copper , copper axes 2 , 3 baths stone ax , 1 card can wear strap hole shape charms , including 2 special venting bronze statue ( only recovered 1 ) . The description form the vent ( pangolin - " Manis javanica " ) to 37 cm long , 9.8 cm wide belly , depicting the head quite lively, with a long pointed snout , eyes rounded edges , floating ear , abdomen and tip of tail to express smooth soft skin , creating not only just foot 5 sharp claws like the real thing . This is the largest and heaviest weight ( 3.4 kg ) , is the only specimen showing the animals in mind sculpture and art history circles iconic ancient Dong Nai . 21 templates found out through said cover 4 categories , with many different types of profiles blade shape , size and weight characteristics .

      Phenomena through the collection of grid uncanny , unprecedented in size - about the weight and exquisite decorative patterns over the entire blade geometry - Director - 1 single-chain copper in soil moderate range , so it's hardly a trace of the burial , the oil that is the resting place of the most powerful characters community can only imagine is one treasure ( Tresor ) storage of weapons and objects you the ancient Dong Nai . These similar warehouses storing weapons - tools available in State Don Most Gia Trang , An Ocean ( Hunan - China ) , at the Ice House , The Field , filled in Dong Son bronze drum or the warehouse name Celebrity co thousands nose Loa ( Hanoi) . Along with the presence of weapons category through the vertical type , Bau Hoe , Go turn ; Long Giao collection shows familiar weapons and are favored by people in this vast land is an existing archaeological objects belong to the period of the Iron relatively common - when that tool - iron weapons appeared , the silhouette complete - powerful enough to remove the brass artifacts correspond to incremental ore sources rare due to import capital for training large cast of strange artifacts and objects through vent style Long Giao . This is the time equivalent of the C14 dating of the " Plain of Jars " Hoa Phu - Suoi Da or cloth under both Megalith tombs discovered at Hang Gon - TNK half after I tr.CN. Thus, the collection through Long Giao , with the characteristics associated with the group originated through " precursor " of it in vertical , Go turn , Bau Hoe , is most fully expressed basic characteristics of this category of weapons in extreme Southeast and South Central . We clearly distinguish the products of the same type of other cultures in Central Highlands ( North China - Chinese China - Inner Mongolia , Sichuan ) , Dong Son or Thailand , but on the other hand contain many similarities details of the types and patterns of geometric decoration through Dong Son ( Elephant Mountain ) or Thailand ( Ban Dhart , Ban Chiang - Udon Thani Udorn , Nan Mu'ong ) . The main features have contributed close to existing multi -line relationships , scale and stature of the culture of Dong Nai with metal centers of civilization in Vietnam and other Southeast Asian mainland .

      In that aspect , if past form arising from Doc Long Giao Pagoda - Go turn , the pattern and the source of its inspiration from the style started its excellent Vietnamese ancient Bronze Age civilization that the world scientific community still called " Dong Son style " ( Dongsonian Style ) . Oil does not have the humanoid dancing costume - sailing - pounding rice - hunt or battle armor , no fish - birds - animal or low as in the past - the Dong Son drums , but other simple motifs of Dong Son Long was the artist collected and filtered communication because they fit the soul and core of their traditional ways . The flowering of decorative geometric patterns of shadow carry on Dong Son Bronze Long Giao is indirect evidence supporting the presence of the Dong Son bronze drums ( Heger I) in Binh Phu - Phu Chanh - Vung Tau - Bu Dang - Phuoc Long time Iron and preliminary integration of Vietnamese ancient life on life here . Along with drums , the design of this pattern is demonstrated by the relationship of the Dong Son - Dong Nai in the nearly century BC most vibrant - when the sound of rock above integrate traditional voice in the wilderness expectations across the vast delta and the rich vitality . And , if the thesis of H. Loof - Wissowa considered the presence of Heger I drums as the " authority of the Dong Son " in it here in Southeast Asia are correct , the authority is the ancient Dong Son in the Southeast to receive affordable outside in line for the leader , also through co - evidence of courage and Dong Nai ancient power ? And , if the considered opinion of Li Qi through the weapon is revealed for supremacy - the " scepter " or " parliamentary " is intended to equip the captain or leader of one army , are correct , then , Transportation over Long group will allow us to visualize the large and powerful armies respectively - are equipped with this type of weapon in working life - to fight and win the enemies turn and beasts for survival , reconstruction and making this fertile land . Also since then , but the iconic leader - who has the most powerful society in the struggle to preserve the creative material culture - the spirit is exalted ancient Dong Nai .

      Through Transportation Council Long treasure is actually a contribution to our understanding of ancient cultural peak of Dong Nai and her identity in historical heights . When the residents of the Hung Kings and the King Thuc An Duong , with the advantage of terrain ore , led the bronze weapons to their peak in volume - kind of , as a basis for sustainable physical strength to keep Van Lang - Au Lac Iron and peak time profile of the Red River civilization established by the blooming of the drum and clock tower - the work of the intellectual elite Vietnam neck , then at that time , the Bronze East South Vietnam was rapidly passing the vertical flourish - Ban Bo and almost all are tools - iron weapons replaced respectively . It is in this historical moment , through Long Giao - weapons which represents iron hard , especially the ability to express the values ​​and spirit of art , was formed as a beautiful and unique exception of Dong Nai . Ministry of Transportation over Long , thus , organic and attached is a manifestation of the definition for mass crystallization of ancient culture of Dong Nai , which itself has contributed to the identities of the other heights with heights Dong Nai Sa Huynh and Dong Son era Iron . Plus, discover treasure Long Giao Long Giao and through co- located in the province of gathering the most representative monuments throughout the Southeast for the early Iron - Spring ferret groups monument - in the province of Phu Hoa Xuan Loc - Long Khanh affordable it also suggests a land of ancient cultural center of Dong Nai - a land of many production tools - iron weapons , splendid jewels , massive stone graves and your grave dense , circular statue rare , have authority over and drums - is a land of each gathering center , a spiritual center of the ancient echo of Dong Nai ? And , affordable drum Binh Phu - Phu Chanh - Vung Tau - Bu Dang - Phuoc Long and megalithic tombs Hang Gon is the first indication of the formation and raised a sovereign power structure that goes beyond team leaders have been privileged over the same page , this ethnic community ?

     Detecting treasure and pass Long Giao Long Giao is flashing , a monumental icon of brass and bronze casting industry in the South East its peak : Climax Springs Weasel - Iron Phu Hoa time soon . This is also the highest peak of prehistoric life - Southeast preliminary use - an arduous life and excitedly dispersed through the Millennium before the calendar , with the largest collection of rock Vietnam in Bridge iron - Spring Spirit - Loc - Phuoc Tan , the largest of mold in vertical areas - Silver Bung , for the collection - a knife - crossbows - by hatred throughout nets - car or redwood had never seen Cai Van , the holding of a unique fossil Binh Da - Loc Hoa and warehouses across - Long assign subjects to vent , megalithic tombs populations Hang Gon - the " Dong Nai phenomenon " in the history of the ups and downs of Culture and Civilization South East Asia .​
