The art of milking the Murex snail dates back to the 4th century B.C.
Cleopatra used that procedure to dye the sails of her boat purple with the intent of flattering Caesar. The gathering of those fluids is a tradition that has been passed down from generation to generation. The Murex snail discharges a milky-white secretion that changes color when exposed to air and light. This transformation begins with a shade of yellow, followed by a pastel green. Finally, under direct sunlight, it turns into a lovely shade of purple, also known as imperial purple.

The women of Boruca use this unique extract to dye the cotton yarn they will use in their weaving. During the waning moon, the Borucans make a memorable trip to the rockiest part of Ventanas beach in Costa Ballena in January and February, knowing that they will find the Murex snails hiding and mating along the rocks.

It is a dangerous and treacherous work to find and "milk" the snails. Doña Marina and others pull the snails off the slippery rocks at Ventanas beach. They proceed to blow on them very carefully to cause the snails to release the fluid, letting it drip over the yarn they are holding. This fluid cannot be stored; therefore, the yarn has to be dyed on site.

The Borucans are one of two indigenous groups remaining in the world that use this process. They preserve the life of these snails by returning them to the rocks after taking the fluid.
Doña Marina goes to the Farmers' Market in Uvita almost every Saturday morning. Her weavings and carved masks are also available at Pacific Edge Cabins in Dominicalito.
