Bloodletting--purposefully cutting the human body to release blood--is an ancient ritual, associated with both healing and sacrifice. Bloodletting was a regular form of medical treatment for ancient Greeks, with its benefits debated by scholars such as Hippocrates and Galen.
Bloodletting in Central America
Bloodletting or auto-sacrifice was a cultural trait of most of the societies in Mesoamerica, beginning with the Olmec perhaps as early as 1200 AD. This type of religious sacrifice involved a person using a sharp instrument such as an agave spine or shark's tooth to pierce a fleshy part of his own body. The resulting blood would drip onto a lump of copal incense or piece of cloth or bark paper, and then those materials would be burned. According to historical records of the Zapotec , Mixtec, and Maya, burning blood was one way to communicate with the sky gods.
Artifacts associated with bloodletting include shark's teeth, maguey thorns, stingray spines, and obsidian blades. Specialized elite materials--obsidian eccentrics, greenstone picks, and 'spoons'--are thought to have been used for elite bloodletting sacrifices in the Formative period and later cultures.
A so-called "bloodletting spoon" is a type of artifact discovered on many Olmec archaeological sites. Although there is some variety, the spoons generally have a flattened 'tail' or blade, with a thickened end. The thick part has a shallow off-center bowl on one side and a second, smaller bowl on the other side. Spoons usually have a small hole pierced through them, and in Olmec art are often depicted as hanging from people's clothing or ears.
Bloodletting spoons have been recovered from Chalcatzingo, Chacsinkin, and Chichén Itzá; the images are found carved in murals and on stone sculptures at San Lorenzo, Cascajal, and Loma del Zapote.
Olmec Spoon Functions
The real function of the Olmec spoon has long been debated. They're called 'bloodletting spoons' because originally scholars believed them to have been for holding blood from auto-sacrifice, the ritual of personal bloodletting. Some scholars still prefer that interpretation, but others have suggested spoons were for holding paints, or for use as snuffing platforms for taking hallucinogens, or even that they were effigies of the Big Dipper constellation. In a recent article in Ancient Mesoamerica, Billie J. A. Follensbee suggests Olmec spoons were part of a hitherto unrecognized toolkit for textile production.
Her argument is in part based on the shape of the tool, which approximates bone weaving battens recognized in several Central American cultures, including some from Olmec sites. Follansbee also identifies several other tools made of elite greenstone or obsidian, such as spindle whorls, picks, and plaques, that could have been used in weaving or cord-making techniques.
