Serapis was an anthropomorphic god created by the Greek pharaoh Ptolemy I. Ptolemy I chose Serapis to be the official god of Egypt and Greece. He hoped a common religious base would unify the two peoples and ease tension in the country. Serapis' attributes were both Egyptian and Hellenistic. Serapis became very popular and his cult quickly spread from its center in Alexandria.
"In the city on the borders of Egypt which boasts Alexander of Macedon as its founder, Sarapis and Isis are worshiped with a reverence that is almost fanatical. Evidence that the sun, under the name of Sarapis, is the object of all this reverence is either the basket set on the head of the god or the figure of a three-headed creature placed by his statue. The middle head of this figure, which is also the largest, represents a lion's; on the right a dog raises its head with a gentle and fawning air; and on the left the neck ends in the head of a ravening wolf. All three beasts are joined together by the coils of a serpent whose head returns to the god's right hand which keeps the monster in check."
