In Greek mythology, Eumaeus (/juːˈmiːəs/; Greek: Εὔμαιος, Eumaios) was Odysseus's swineherd and friend. His father, Ktesios son of Ormenos was king of an island called Syria. When he was a young child a Phoenician sailor seduced his nurse, a slave, who agreed to bring the child among other treasures in exchange for their help in her escape. The nurse was killed by Artemis on the journey by sea, but the sailors continued to Ithaca where Odysseus' father Laertes bought him as a slave. Thereafter he was brought up with Odysseus and his sister Ctimene (or Ktimene), and was treated by Anticleia, their mother, almost as Ctimene's equal.
In Homer's Odyssey, Eumaeus is the first mortal that Odysseus meets upon his return to Ithaca after fighting in the Trojan War. He has four dogs, 'savage as wild beasts,' who protect his pigs. Although he does not recognise his old master — Odysseus is in disguise — and has his misgivings, Eumaeus treats Odysseus well, offering food and shelter to one whom he thinks is a mere indigent. On being pushed to explain himself, Odysseus spins a distorted tale, misleading Eumaeus into believing that he is the son not of Laertes but of Castor.
The swineherd refuses to accept the vow that Odysseus, whom he loves above all others (rendering him especially bitter towards the suitors), is finally on his way home. Having heard such assurances all too often, and been deceived by a prevaricator from Aetolia, Eumaeus has become inured to them. "Don't you try to gratify or soothe my heart with falsehoods," he cautions:
