Érimón

Érimón[2] (Modern Irish: Éireamhón), commonly Anglicised as Heremon, son of Míl Espáine (and great-grandson of Breoghan, king of Celtic Galicia), according to medieval Irish legends and historical traditions, was one of the chieftains who took part in the Milesian invasion of Ireland, which conquered the island from the Tuatha Dé Danann, and one of the first Milesian High Kings.

Érimón became sole ruler of Ireland and built his capital at Ráth Oinn (later site of Rathdown Castle, on the east coast near modern Greystones).

He gave Leinster to Crimthann Sciathbél of the Fir Domnann; Munster to the four sons of Eber Finn, Ér, Orba, Ferón and Fergna; Connacht to Ún and Étan, sons of Uicce; and Ulster to Eber mac Ír.

[7] However, the idea remains seductive to some commentators,[8] on the basis of the coincidence of the similar sound between the two names, that they both are mythological founders of two separate great Indo-European cultures, the inclusion of the M-N- sound in their respective names, and the fact that many of the great Indo-European cultural traditions’ founders share the same M-N- laden moniker.

Through his son, Íriel Fáid, Érimón was the progenitor of the Heremonians and provided many High Kings of Ireland.
