Definition of Eueriio

It was not until the Bronze Age, about 600 or 500 B.C., that the Goidels, the first invaders speaking a Keltoi language, set foot in Ireland. The Keltoi tribe called the Euerni/Iverni or Erainn, who belonged to the Belgae people of northern Gaul and Britain, began arriving in modern day Ireland around this time and there is good reason to believe from Ptolemy's account of Ireland that the Euerni tribes became the most widespread and predominant on the island.
