What is the name of Odysseus's faithful swineherd?

Odysseus’s faithful swineherd is Eumaeus.

Eumaeus is Odysseus’s loyal servant, friend, and keeper of the royal pigs. Although he does not recognize Odysseus when the king returns in disguise, he welcomes the apparent beggar, offers him food and shelter, and speaks warmly of the absent ruler.

The Odyssey gives Eumaeus a detailed personal history. He was born to Ctesius, king of the island of Syria, but was kidnapped as a child and sold to Laertes, Odysseus’s father. He was raised alongside Odysseus and his sister Ctimene, which helps explain the depth of his loyalty.

Eumaeus is the first person Odysseus visits on Ithaca after returning from the war. He later welcomes Telemachus and helps Odysseus and his son overthrow the suitors. Readers often confuse him with Philoetius, the loyal cowherd, or Melanthius, the disloyal goatherd; Eurycleia is the palace nurse.
