Pre-Inca Diaguita decorative patterns present a visual logic, characterized by the use of complex symmetries, optical illusions, an endless variety of simple geometric forms, horror vacui, hypnotic attraction and other techniques. These aspects, as well as the association of this visual art with an animal alter ego (jaguar) and evidence of the use of hallucinogenics, suggest a cultural link with specific ethnographic (shipibo-conibo) and archaeological (mojocoya) visual art. We propose that in this case we are dealing with visual "technologies of enchantment" (Gell 1998) that are deemed to have social agency and captivate the viewer with extremely complex, apparently animated non-mimetic abstract patterns. In ethnographic contexts, similar decorative patterns play an important role in shamanic healing strategies.
