Prior to the arrival of sons of King Milesius the mythological tribes in Ireland were said to include the the Fomorians (Fomhóire), the Partholonians, the Nemedians, the Fir Bolgs and the Tuatha de Danann. Stories of these people are among the more prominent among the pre-historical accounts of ancient Hibernia (Eire, Ireland).
From Geoffrey Keating’s Foras Feasa ar Éirinn (The History of Ireland) comes the following paragraph:
“The Book of Invasions states that it was, three hundred years after the Deluge that Parthalon came, and that his descendants remained in possession of Ireland three hundred years, and that Ireland remained a waste for thirty years, till the descendants of Neimhidh arrived there, and that these descendants ruled Ireland two hundred and seventeen years, and that the Firbolg held the sovereignty thirty-six years, and the Tuatha Dé Danann two hundred years less by three; and, adding all these together, they make a total of one thousand and eighty years from the Deluge to the coming of the sons of Milidh (Milesians) to Ireland.”
