in Greek mythology, one of a tribe encountered by the Greek hero Odysseus during his return from Troy, after a north wind had driven him and his men from Cape Malea (Homer, Odyssey, Book IX). The local inhabitants, whose distinctive practice is indicated by their name, invited Odysseus' scouts to eat of the mysterious plant. Those who did so were overcome by a blissful forgetfulness; they had to be dragged back to the ship and chained to the rowing-benches, or they would never have returned to their duties. The 5th-century-BC historian Herodotus located the Lotus-Eaters on the Libyan coast. Alfred, Lord Tennyson brought the story to the modern world in his poem "The Lotos-Eaters" (1832).

The Greeks called several non-narcotic plants lōtos, but the name may have been used in this case for the opium poppy, the ripe seed pod of which resembles the pod of the true lotus. The phrase “to eat lotus” is used metaphorically by numerous ancient writers to mean “to forget,” or “to be unmindful.”
