Ancient Amazonian Earthwork Roads
By using satellite images, this study confirms 350 km of ancient roads, comprising 634 wide and 321 narrow roads, in southwestern Amazonia’s earthwork-rich landscape. The roads were straight, mostly under 500 m long, but with some extending several kilometers. They occurred most prevalently in areas of dense earthwork. Nested earthworks were more road-rich than simple ones, and roads were more common in structures with quadrilateral rather than r…
Refining the Chronology and Occupation Dynamics of the Mound Villages of South-Eastern Acre, Brazil
This paper summarises recent test excavations at five Mound Village sites in the south-eastern sector of Acre state, Brazil, including Caboquinho, Boa Esperança, Tocantins, Dos Circulos IV and V. Radiocarbon dates obtained from the excavation of this site refine the chronology of this archaeological tradition. To improve the chronologies of the mound villages in Acre for which radiocarbon dates were available, we modelled them using Bayesian stat…
The geoglyph sites of Acre, Brazil
Hypotheses concerning climatic change during the Amazonian Holocene often assume that the presence of ancient charcoal from forest fires indicates periods of drier climate in the past. These theories, however, neglect the possibility that such charcoal may result from early human activity. This article presents new evidence of anthropogenic ash and charcoal accumulation in the state of Acre, Brazil, dating back toc. 10 000 cal BP, which questions…
New radiometric dates for precolumbian (2000–700 b.p.) earthworks in western Amazonia, Brazil
In this paper we present new data on the precolumbian geometric ditched enclosures identified in Acre State, western Amazonia, Brazil. Remote sensing and ground survey have revealed 281 earthworks, located mainly on the edges of high plateaus overlooking the river valleys drained by the southeastern tributaries of the Upper Purus River. Excavations have shown that the few existing cultural materials are concentrated on the slopes and in the botto…
Construindo paisagens como espaços sociais
Esse artigo dedica-se a examinar com detalhes a arquitetura monumental dos geoglifos, gigantescos espaços de sociabilidade que demarcavam lugares e disciplinavam deslocamentos na Amazônia Ocidental pré-colombiana. Esses lugares são examinados sob a perspectiva da ecologia histórica, a partir da qual se entende os fenômenos produzidos pela relação dialética entre sociedades humanas e meio ambiente e que resultam na formação das paisagens como pali…
