And as they were advanced in literature and politics, the religion of earth, so they assiduously cultivated religion, the politics of heaven. The Biblical student has found among the tombs of Nile-land the absolute truth of what Celsus said—namely, that the Hebrews borrowed their tenets and practices from Egypt. Their date of the creation _ex nihilo_ (B.C. 4004–4620) was evidently Manetho’s period of the succession of Mena, and it is used even in our day. Their genesitic cosmogony, as Philo Judæus shows, and as Origen expressly declares, was an adaptation of Nilotic allegories and mysteries which the vulgar understood factually and literally. Their ‘Adam’ suggests ‘Atum,’ whence ‘Adima,’ the First Man amongst the Hindus. Their App or Apap (Apophis), whose determinative is a snake transfixed with four knife-blades,[472] is the great old serpent, the ophid-giant, Sin, Sathanas. The ‘Flood’[473] is the annual Nilotic inundation modified by the Izdubar legends of the Interamnian Plain. Noah, Nuh, Nöe, is suspiciously like Nu or Nuhu,[474] the Sailor of the Waters, the Lord of the Full Nile. Ham suggests Kam, the black race. The ark is the Bahr or Ua (Baris, Argo navis) of Nu, the sacred vessel portrayed in the ruins of Egyptian Elephanta, the boat of Osiris, or Uasur, the man-formed Sun-god; and the floating cradle of Moses is a mere replica of Osiris’ ark. In that complicated idolatry of deceased ancestors, based upon a system of monotheism,[475] or rather the worship of glorified man, which formed the religion of Egypt, the Sun typified human life. He rose as the infant Horus; he was the Lord Ka of the mid-day; as Tum he became old and set; and as Hormakhu (Harmachis) he shone to the under world below the horizon, Night and Death being the forerunners of Light and Life.[476]
