The kapala is a sacred sculpted cup made from the top of a human skull frequently offered by Hindu and Buddhist worshipers to their fierce deities.

A legacy of the ancient tradition of human sacrifice, the kapala is nowadays perceived as a dark but fascinating form of sculpture. Tibetan kapalas, in particular, feature impressive bas-relief artworks depicting religious figures and scenes, and are often adorned with semi-precious stones and silver-work. The elaborate carvings were handmade and the skull was soaked in water to soften the bone.

In Tibet, skull cups are used at Buddhist altars to offer wrathful divinities either wine, which symbolizes blood, or dough cakes shaped as human eyes or ears. Through the force of tantric visualization based on meditation and deep philosophical study,  a sort of transubstantiation will occur and the wine will be transformed into the Wisdom Nectar, a liquid form of the enlightened mind of one or all the deities in the Celestial Palace of the Mandala. This is just one of the many uses of the kapala in Tibetan ritual culture.

Some modern-day kapalas are still shaped like the top of a human skull, but they are made of brass and while they are adorned with artistic motifs, they aren’t nearly as fascinating as  genuine human skull cups.
