The infamous lettuce scene started the very night of Horus’ victory. Happy to have found a replacement for Osiris, the gods decided to throw a party, inviting everyone in Egypt. As there were so many gods invited, some of them had to share the tents, including Horus and Seth. The latter took advantage of this arrangement by stealthily making his way towards Horus’ bunk when everyone was asleep, and ejaculate on his body. But Horus had sensed the presence of Seth (and his intentions) and caught his semen in one hand, not letting it touch his body. When he told his mother about this, Isis quickly cut off his hand and threw it in the Nile. Meanwhile, she proceeded to collect her son’s semen and went to ask the gods’ gardener which of the vegetables he was growing were Seth’s favorite. The gardener pointed to the
lettuce, and that was where Isis deposited Horus’ semen.
Later that day, after a delicious meal of fresh lettuce, Seth stood up in the middle of the room where every god was gathered in celebration and he claimed that he had an announcement to make. He then told everyone in attendance that he had “done the male’s work” on Horus and that this fact was proof enough that Seth would make a better king than Horus. But when he “called” his own seed, it replied from the middle of the river, not from Horus’ body as he had expected. Instead, when Isis stepped in to call her son’s semen out, it replied from Seth’s forehead. Thus it was apparent to everyone there that Seth had the “male’s work” done to him. It had become clear that Horus was the victor in that contest.
