Calu
Calu is an epithet of the Etruscan chthonic fire god Śuri as god of the underworld, roughly equivalent to the Greek god Hades ; moreover, as with Hades, this god-name was also used as a synonym for the underworld itself.
He is identified by his wolf attributes, such as a wolf-like appearance or a human with a wolf-skin cap.
The visual representations of the cult of Calu seem to contain common elements with the Roman cult of Lupercalia and the Faliscan cult of the Hirpi Sorani.
