In the twelfth book of Homer's Odyssey, Odysseus and his men are on the island of Thrinacia. On this island the cattle of the sun god have their pasture. Odysseus and his men have been warned against harming these cattle, but Odysseus falls asleep and his men, who are very hungry, kill some of the cattle and eat them.
After consuming some of the cattle, the poet writes: "The ox-hides crawled about, raw meat and roast bellowed on the spit, and all around sounded the noise of lowing cattle" (A.S. Kline translation).
These, then, are the "mind tricks" that the gods play on Odysseus' men.
