The cult of Serapis was introduced during the third century BC on the orders of Pharaoh Ptolemy I Soter of the Ptolemaic Kingdom as a means to unify the Greeks and Egyptians in his realm. A serapeum was any temple or religious precinct devoted to Serapis. The cultus of Serapis was spread as a matter of deliberate policy by the Ptolemaic kings, who also built the immense Serapeum of Alexandria. Serapis continued to increase in popularity during the Roman Empire, often replacing Osiris as the consort of Isis in temples outside Egypt. Cerberus was a three-headed dog that guarded the entrance of the Underworld.
