A king was called "Pharaoh" is ancient Egypt. A Pharaoh asked -
"Who is the greatest of the gods ?"
"I am not" - said Horus (Horus is a god of the sky and kingship)
"Anubis is" - said Isis (Isis is a goddess of health, marriage, and wisdom)
"Isis is lying" - said Anubis (Anubis is protector of the dead)
The Pharaoh knew that only one of the gods is telling the truth - the other two were lying. Who is the greatest of the gods ?
