What is the ancient tradition of the Mixtec people?

The Mixtec people have a 1,500-year-old tradition of collecting a radiant purple dye, known as tixinda, from marine snails, which is integral to their textiles and beliefs.

Why is the Mixtec purple dye tradition under threat?

The tradition is threatened by intense poaching, habitat disruption, and a scientific debate over the snails' species classification, which impacts conservation efforts.

What is being done to save the Mixtec dyeing tradition?

Scientists are collaborating with Mixtec artisans to conduct genetic and anatomical analyses to identify the snail species definitively, aiming to secure conservation and preserve the tradition.

Mixtec Artisans Fight to Save Sacred Purple Dye Tradition

The Mixtec people of Oaxaca, Mexico, have a 1,500-year-old tradition of collecting a radiant purple dye from marine snails, known as tixinda. This sacred dye symbolizes fertility and death, and is integral to Mixtec textiles and beliefs. However, this ancient practice faces significant threats, including intense poaching pressure and habitat disruption following a 2020 earthquake. Decades ago, these snails were abundant, but populations have drastically declined, partly due to unsustainable harvesting practices in the 1980s.

Conservation efforts in 1988 secured federal protections for the snails, scientifically identified then as Plicopurpura pansa. Yet, recent scientific studies suggest these snails may belong to a different, unprotected species, P. columellaris, casting doubt on current legal protections. This taxonomic uncertainty creates a loophole, potentially allowing for the harvesting of these mollusks without legal repercussions and jeopardizing the survival of the Mixtec dyeing tradition.
