This bottle depicts a huaco bifronte (of two faces man and woman) of the pre-Inca culture "tiahuanaco". Huaco is the generic name given in Peru mostly to earthen vessels and other finely made pottery artworks by the Indigenous peoples of the Americas found in pre-Columbian sites such as burial locations, sanctuaries, temples and other ancient ruins. Huacos are not mere earthenware but notable pottery specimens linked to ceremonial, religious, artistic or aesthetic uses in central Andean, pre-Columbian civilizations.
