The Laestrygonians

From LitWiki

The [Laestrygonians] are a race of man eating giants that live off of a stone-walled stronghold island of Lamos. The people of Lamos earn twice the wages to those who never sleep. They are a people of great survival instincts that lay awake for the sheep may be stolen. They are also eaters of men or [Cannibals]. There was a wagon road to the house of Antiphates, king of the Laestrygonians. Odysseus and his men soon found out the horror of the uncivilized man. Antiphates gorged and tore Odysseus' men to bits and chased them off with his giant friends with boulders in slings. Odysseus screamed to his men as they were rowing away "'man the oars and pull til your hearts break/if you would put this butchery behind!'" (X.136-7)
