El Horizonte corrugado: correlaciones estilísticas y culturales

On all the periphery of the Amazon basin, corrugated styles appeared more or less simultaneously around the end of the first millenary AD, indicating a distinctive «Horizon» that resulted from complex socio-cultural processes. In fact, the presence of these ceramics in the Equatorian Amazon as well as in some Andean valleys seems closely related to the settlement and to the subsequent movements of populations belonging to the linguistic Jibaroan subgroup. The presence of corrugated wares to the north and to the south of this area is due to different processes of diffusion, which implied other ethnic groups. Therefore, the corrugated style seems to be part of an «Amazonian background», and was probably linked to some cultural (chicha production) and ritual (funeral urns) practices.
