Inca (Inka)
more object details

General Description

Knives with a half-moon shape (tumi) are common in the ancient Andes. This wide blade and short handle form became popular by the Late Horizon (1400-1532 CE). While the knives were produced with metal alloys, examples with plating and gilding also exist for presumed ceremonial function. By the Late Horizon, tin bronze was promoted alongside the more common arsenical bronze; the tin provided not only more strength to the knives but also an original yellow-gold color.

This knife is decorated by elaborate zigzags down the shaft and a modeled human figure riding an animal, possibly a feline. Open loops on less decorative examples may have provided for suspension, presumably carried around the neck of a warrior.
