Bitru
Otherwise called Sytry, a great Prince of Hell, according to the demonographer Wierius. He appeared in the form of a leopard with the wings of a griffin. But when he adopted a human appearance for the nonce it was invariably one of great beauty. It is he who awakes lust in the human heart. Seventy legions obey his commands. Bitumen, in Magic: Bitumen was greatly used in magical practices. Images for the purpose of sympathetic magic were often made of this substance; and it was used in the ceremonies for the cleansing of houses in which any uncleanness had appeared-being spread on the floor like clay.
