托勒密六世
Fergus Fortamail ("strong, prevailing"), son of Bresal Brecc, son of Óengus Ollom, son of Ailill Bracan, son of Labraid Loingsech, was, according to medieval Irish legend and historical tradition, a High King of Ireland. He took power after killing the previous incumbent, Eochaid Ailtlethan, in battle, and ruled for either eleven, twelve or twelve and a half years, until he was killed by Eochaid's son Óengus Tuirmech Temrach in battle at Tara. The "Lebor Gabála Érenn" synchronises his reign with that of Ptolemy VI Philometor in Egypt (180–145 BC). The chronology of Geoffrey Keating's "Foras Feasa ar Éirinn" dates his reign to 274–262 BC, that of the "Annals of the Four Masters" to 396–385 BC.
