In the year 363 of the reign of Ra-Horakhti upon the earth it befell that the god was in Nubia with a mighty army. Set, the Evil One, had rebelled against him, for Ra was advanced in years, and Set was of all beings the most cunning and treacherous. He it was also who had slain his twin-brother Osiris, the great and good king ; and for this reason Horus, the brother of Osiris, desired greatly to have his life.
With his chariots and horsemen and foot-soldiers Ra embarked on the Great River and came to Edfû, where Horus of Edfû joined him.
” O Ra,” said Horus, “great are thine enemies, and cunningly do they conspire against thee ! “
“My son,” answered Ra, ” arm thee and go forth against mine enemies, and slay them speedily.”
Thereupon Horus sought the aid of the god Thoth, the master of all magic, by whose aid he changed himself into a great sun-disk, with resplendent wings outstretched on either side. Straight to the sun he flew, and from the heavens he looked so fiercely upon his enemies and Ra’s, that they neither heard nor saw aright. Each man judged his neighbour to be a stranger, and a cry went up that the foe were upon them. Each turned his weapon against the other, the majority were slain, and the handful of survivors scattered. And Horus hovered for a while over the battle-plain, hoping to find Set, but the arch-enemy was not there; he was hiding in the North Country.
Then Horus returned to Ra, who embraced him kindly. And Horus took Ra and the goddess Astarte, and showed them the battlefield strewn with corpses.
Ra, king of the gods, said to those in his train: “Come, let us voyage to the Nile, for our enemies are slain.” But Set still had a large following, and some of his associates he commanded to turn themselves into crocodiles and hippopotami, so that they might swallow the occupants of the divine barque and yet remain invulnerable by reason of their thick hides. Horus, however, had gathered his band of smiths, each of whom made for himself an iron lance and a chain, on which Thoth bestowed some of his ever-powerful magic. Horus also repeated the formulae in the Book of Slaying the Hippopotamus. So that when the fierce animals charged up the river the god was ready for them; many of them were pierced by the magic weapons and died, while the remainder fled. Those who fled to the south were pursued by Horus, and were at length overtaken. Another great conflict ensued, wherein the followers of Set were again vanquished. According to the desire of Ra, a shrine was raised to commemorate the victory, and his image placed therein. Yet another encounter, however, was to take place in the South Land ere the followers of Set were utterly destroyed.
