“That day they made preparations for the passage over; and on the following they waited for the sun, as they wished to see it rising, in the meantime burning all sorts of perfumes on the bridges, and strewing the road with myrtle branches. When the sun rose, Xerxes, pouring a libation into the sea out of a golden cup, offered up a prayer to the sun, that no such accident might befall him as would prevent him from subduing Europe, until he had reached its utmost limits. After having prayed, he threw the cup into the Hellespont, and a golden bowl and a Persian sword, which they call _acinace_. But I cannot determine with certainty, whether he dropped these things into the sea as an offering to the sun, or whether he repented of having scourged the Hellespont and presented these gifts to the sea as a compensation.”[68] Purity Sought through Baptism. The pagan conception that water produced spiritual purity was expressed in many ways. JUVENAL describes the custom of Roman women who sought to expiate their sins, committed in licentious revelries, as follows: “She will break the ice and plunge into the river in the depth of winter, or dip three times in the Tiber at early dawn, and bathe her timid head in its very eddies, and thence emerging, will crawl on bending knees, naked and shivering, over the whole field of the haughty kings [the Campus Martius]. If white Io command, she will go to the extremity of Egypt, and bring back water fetched from scorching Meroe, to sprinkle on the temple of Isis, that rears itself hard by the sheep-fold. For she believes that the warning is given her by the voice of the goddess herself.”[69] Mithraic and Gnostic Baptism. The conception that water cleansed from sin was a prominent feature in Mithraicism and in gnosticism. KING, who is authority on all gnostic questions, says: “In my account of Mithraicism, notice has been taken of the very prominent part that sacraments for the remission of sin play in the ceremonial of that religion; the following extracts from the grand Gnostic text-book will serve to show how the same notions, (and probably forms) were transferred to the service of Gnosticism. “‘_Baptism Remitting Sins._’--(_Pistis-Sophia_) (298).
