The bottle was one of the most favored forms for expressions of Central Andean Pre-Columbian art. These containers offered a platform for a diverse array of iconographies, although they were made as funerary offerings and not for actual use. The stirrup spout is said to symbolize duality or the fusion of opposites, though in truth we cannot be sure what it symbolizes. We do know, however, that such spouts remained a very important traditional element of funerary bottles for thousands of years in this part of the world.
