In Greek mythology Agreus or Argeus and his brother Nomios are two of the Panes, creatures multiplied from the god Pan. They are human in shape, but have the horns of goats. Like Pan, both were the sons of Hermes, Argeus' mother being the nymph Sose, a prophetess: he inherited his mother's gift of prophecy, and was also a skilled hunter. Nomios' mother was the dryad Penelope (not the same as the wife of Odysseus). He was an excellent shepherd, a seducer of nymphs, and musician upon the shepherd's pipes. Agreus and Nomios could also be understood as epithets of Pan, expressing two different aspects of the prime Pan, reflecting his dual nature as both a wise prophet and a lustful beast. Both Agreus (meaning "hunter") and Nomios (meaning "shepherd") are titles of several agricultural gods, including Aristaeus and Pan himself.
Agreus was also the name of several other mythological characters.
- Agreus, a son of Apollo and Euboea, daughter of Macareus. He was the lord of Diphys in Euboea, or king of the entire island.
- Agreus, a warrior from Pylos, yet another of the army of the Seven Against Thebes. He was killed by Menoeceus, son of Creon.
Agreus in popular culture
- Agreus is an antagonist in the video game Castlevania: Lords of Shadow 2. He is the brother of the old god Pan, who in the previous game fought Gabriel Belmont in order to provide a blood sacrifice needed to reach the final Lord of Shadow, the Lord of Death. Agreus and Pan were the old gods who governed the balance of nature, however when Pan died, Argeus was forced to shoulder the natural balance himself and his anger and grief over his brother's death, caused him to unleash famine and plague on the world. He is further enraged after Gabriel becomes the powerful vampire Dracula and views Pan's sacrifice as foolish and naive. Agreus plans to take his revenge on Dracula and at some point obtains a piece of the broken Mirror of Fate. While searching for the fragments of the mirror, Dracula encounters Agreus and attempts to reason with him that his brother's sacrifice was for a cause that he believed in, but Agreus retorts that he only killed him due to his quest for world domination. He hunts Dracula in a garden maze and then challenges him in combat, which Dracula wins by crushing Agreus' skull.
