Anubis

One of the roles of Anubis in ancient Egyptian belief was the weighing of the heart. After death, Anubis would compare the deceased's heart to an ostrich feather representing truth. If the heart was heavier (therefore impure), the demon Ammit would devour the soul. Otherwise the soul would go on to immortality with Osiris. Inquisitor88 depicts Anubis and his scales.
