Notes: The god Serapis is a classic example of the use of religion to reinforce political and cultural unification following a foreign conquest and occupation. According to Tour Egypt, "Serapis (Sarapis, Zaparrus) was an invented god. He was a composite of several Egyptian and Hellenistic deities who was introduced to the world at the beginning of the Ptolemaic (Greek) Period in Egypt during the reign of Ptolemy I, though his legacy lasted well into the Roman period. Thus, he was meant to form a bridge between the Greek and Egyptian religion in a new age in which their respective gods were bought face to face with each other, so that both Egyptians and Greeks could find union in a specific supreme entity."
Serapis existed in Egypt before the Ptolemies took over the kingdom following the death of Alexander the Great. According to the Oxford Classical Dictionary (OCD, 3rd ed. revised), "Sarapis ... was the hypostasis of Osiris and of Apis-bulls entombed at Saqqara." Just as the Ptolemies made themselves pharoahs after the takeover, the Greeks took over the existing cult of Sarapis "to provide themselves with a divine Graeco-Egyptian patron." (OCD) By doing so, they were following Alexander's own model of fusing cultures in order to enhance his own political control over his subject populations.
