Anubis is one of the most iconic gods of ancient Egypt, often depicted as a man with the head of a jackal. Anubis would weigh the afterlife petitioner's heart against the feather of Maat, the goddess of justice and truth herself. When placed against the petitioner's heart, it judged their life and morality. If they were a good person, the feather would be heavier than their heart and sink. If they were a bad person, their heart would sink.
