Serapis (, Attic/Ionian Greek) or Sarapis (, Doric Greek) is a Graeco-Egyptian  god. The Cult of Serapis was introduced during the 3rd century BC on the orders of Ptolemy I of Egypt as a means to unify the Greeks and Egyptians in his realm. The god was depicted as Greek in appearance, but with Egyptian trappings, and combined iconography from a great many cults, signifying both abundance and resurrection. A serapeum (Greek serapeion) 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 an immense Serapeum in Alexandria.
