Godfrey Higgins notes that Soros was the name given by the Egyptians to a stone coffin, and Apis was Osiris incarnated in the sacred bull. These two words combined result in Soros-Apis or Sor-Apis, “the tomb of the bull.” Among other meanings suggested for the word Serapis are: “The Sacred Bull,” “The Sun in Taurus,” “The Soul of Osiris,” “The Sacred Serpent,” and “The Retiring of the Bull.” The last appellation has reference to the ceremony of drowning the sacred Apis in the waters of the Nile every twenty-five years.
