Talthybius
The herald of Agamenmon at Troy. (Iliad of Homer; Herodotus) He was worshipped as a hero at Sparta and Argos, where sacrifices also were offered to him. ( Pausanias iii; Herodotus vii. 134.)
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom Herodotus The History. The Seventh Book: Polymnia
On the Lacedaemonians, however, the wrath of Talthybius, Agamemnon’s herald, fell with violence. Talthybius has a temple at Sparta; and his descendants, who are called Talthybiadae, still live there, and have the privilege of being the only persons who discharge the office of herald. When therefore the Spartans had done the deed of which we speak, the victims at their sacrifices failed to give good tokens; and this failure lasted for a very long time. Then the Spartans were troubled; and, regarding what had befallen them as a grievous calamity, they held frequent assemblies of the people, and made proclamation through the town, “Was any Lacedaemonian willing to give his life for Sparta?” Upon this two Spartans, Sperthias, the son Aneristus, and Bulis, the son of Nicolaus, both men of noble birth, and among the wealthiest in the place, came forward and freely offered themselves as an atonement to Xerxes for the heralds of Darius slain at Sparta. So the Spartans sent them away to the Medes to undergo death.
From The Iliad of Homer. Book XIX
Agamemnon then rose, and Talthybius whose voice was like that of a god came to him with the boar. The son of Atreus drew the knife which he wore by the scabbard of his mighty sword, and began by cutting off some bristles from the boar, lifting up his hands in prayer as he did so. The other Achaeans sat where they were all silent and orderly to hear the king, and Agamemnon looked into the vault of heaven and prayed saying, "I call Jove the first and mightiest of all gods to witness, I call also Earth and Sun and the Erinyes who dwell below and take vengeance on him who shall swear falsely, that I have laid no hand upon the girl Briseis, neither to take her to my bed nor otherwise, but that she has remained in my tents inviolate. If I swear falsely may heaven visit me with all the penalties which it metes out to those who perjure themselves."
[3.9] Menelaus went with Ulysses and Talthybius to Cinyras in Cyprus and tried to persuade him to join the allies. He made a present of breastplates to the absent Agamemnon, and swore he would send fifty ships, but he sent only one, commanded by the son of Mygdalion, and the rest he moulded out of earth and launched them in the sea.
From Seneca. Apocolocyntosis
Claudius was charmed to hear his own praises sung, and would have stayed longer to see the show. But the Talthybius [16] of the gods laid a hand on him, and led him across the Campus Martius, first wrapping his head up close that no one might know him, until betwixt Tiber and the Subway he went down to the lower regions.
