What is "eurybates"

In Greek mythology, Eurybates (Εὐρυβάτης) was the herald for the Greek armies during the Trojan War. He served as Odysseus's squire. He was described by Odysseus to Penelope as "round-shouldered, dark-skinned, and curly-haired." Odysseus is said to pay him greater regard than any other of his companions for his honesty and faithfulness.

He, along with Talthybius, were sent by Agamemnon to retrieve Briseis from Achilles' camp.
