A tupilaq (tupilak or ᑐᐱᓚᒃ in Inuktitut syllabics, plural tupilait[1])[2][3] is a monster or carving of a monster.
In Inuit religion, especially in Greenland, a tupilaq was an avenging monster fabricated by an angakkuq (a practitioner of witchcraft or shamanism) by using various objects such as animal parts (bone, skin, hair, sinew, etc.)[3] and even parts taken from the corpses of children. The creature was given life by ritualistic chants. It was then placed into the sea to seek and destroy a specific enemy.
The use of tupilaq was considered risky, as if it was sent to destroy someone who had greater magical powers than the one who had formed it, it could be sent back to kill its maker instead,[4] although the maker of the tupilaq could escape by public confession of their deed.[5]
Because tupilaq were made in secret, in isolated places and from perishable materials, none have been preserved. Early European visitors to Greenland, fascinated by the native legend, were eager to see what tupilaq looked like, so Inuit began to carve representations of them out of sperm whale teeth.
Today, tupilaq of many different shapes and sizes are carved from various materials such as narwhal and walrus tusk, wood and caribou antler. They are an important part of Greenlandic Inuit art, and are highly prized as collectibles.
