The goldsmiths of the Early Quimbaya period (1st - 10th centuries AD)
created a naturalistic art form on the temperate slopes bordering the river
Cauca. Their poporos were inspired by plant forms; others are portraits
with calm faces and stately postures, inside which fragments of calcined
bones have been found. These masters of lost wax casting modelled their
pieces in beeswax and covered them with clay, so that when the mould was
heated the wax left its form on the inside. The gold-copper alloy tumbaga,
poured into the mould, took on the same shape as the wax model.
Towards the 10th century AD the middle Cauca valley was occupied
by other communities who survived until the Spanish conquest. Living in
villages of circular houses, they buried their dead in large cemeteries.
The ornaments of the Late Quimbaya period are of gold and copper in simple
forms, very widely used.
