Clement of Alexandria describes a figure of Serapis compounded from the following elements: First, filings of gold, silver, lead, and tin; second, all manner of Egyptian stones, including sapphires, hematites, emeralds, and topazes; all these being ground down and mixed together with the coloring matter left over from the funeral of Osiris and Apis. The result was a rare and curious figure, indigo in color. Some of the statues of Serapis must have been formed of extremely hard substances, for when a Christian soldier, carrying out the edict of Theodosius, struck the Alexandrian Serapis with his ax, that instrument was shattered into fragments and sparks flew from it. It is also quite probable that Serapis was worshiped in the form of a serpent, in common with many of the higher deities of the Egyptian and Greek pantheons.
