The twin brothers Irosun and Iwori came down to the world together, but Irosun plotted with sixteen witches to be rid of Iwori. A dream warned him; with the goat for Eshú, the hen for Ifá and his Osanyin, which showed him the witches' gatherings, he uncovered the plot, and the bath of leaves set him free.
Before coming down, in Heaven he was advised to sacrifice to a divinity who worked under the cover of a witch —a rooster, kola nuts and palm wine— and to offer a goat to Eshú. Once the sacrifices were done, the twins Irosun and Iwori came down to the world together. Meanwhile, Irosun made a deal with sixteen witches of the night to get rid of Iwori. One night, Iwori dreamed of an execution chamber; since he did not understand the dream, he went for divination, and Ifá told him that they were about to deceive him, though none of it would work if he fed his Ifá a hen and wrapped dried fish and gave a goat to Eshú. He did so, and of the sixteen plotters two died.
It was the Awoses who revealed to him that the plot had been put together by his own younger brother. Iwori had an Osanyin that let him see what happened in the meetings of the witches: he gave it a rooster and powdered yam with ginger leaves, went to the meeting that night and managed to see the tricks of the fourteen who were left. They noticed the intruder and caught him, accusing him of spying, but he disappeared before they could hurt him. When he woke up, Ifá told him to bathe with the leaves the priests would prepare for him; after the bath, the plotters understood that they had been found out, left the place and let him be. When this Ifá comes out, the person is told that their younger brother is a witch who is plotting against them.
