Note 10 — Chapter III
Reading edition
The Athach (otherwise Aitheach) Tuatha Dr. O'Conor translates "giant-race," but it has probably no connection with the word [f]athach, "a giant." O'Curry and most authorities translate it "plebeian," or "rent-paying," and Keating expressly equates it with daor-chlanna, or "unfree clans." These were probably largely if not entirely composed of Firbolgs and other pre-Milesians or pre-Celtic tribes. See ch. XII, note 12.
