La Tolita (Ecuador) culture lasted from ca 600BC to 400AD and produced some 
of the finest pre-Columbian gold artifacts. The goldsmiths worked in gold, silver, 
platinum, tumbaga (an alloy of copper and gold) and copper. This 'sungod 
mask' is its most famous piece, being now the emblem of the Banco Central, but 
it is often erroneously referred to as Inca.     Museo
