• General Notes

  Gabhran mac Domangart Gabhran was a wise and excellent Prince. He first instituted the office of the King's Advocate. He persuaded Loth, a Pictish King, to league with Uter Pendragon, King of the Britons (and who married Pendragon's daughter Ann, sister of King Arthur, of the Round table), against the Anglo-Saxons 502. And when the famous King Arthur mounted the British throne he aided him against the Saxons. Gabhran was at last cut off, for one Toncetus, the Supreme Judge of Capital Crimes, a cruel and covetous man, expecting easy pardon of the King; the enraged people therefore cut him off. But finding they could not obtain the King's mercy, they next slew the King himself at the instigation of one Donald of Athol, 535, reigned thirty-four years. His Queen and children fled to Ireland. (Others say that he died after a tedious sickness and was buried at Icolmkill, the royal burying place). He was succeeded by his nephew, Eugenius III, who instead of revenging his uncle's death, received Donald into favor, which made him suspected of having a hand in the conspiracy; and he was succeeded, in 558, by his brother Congallus, who introduced heraldry, recalled the children of Gabhran, but before they returned he died, 568, reigned ten years, and was succeeded by his younger brother Kintellus, who courteously entertained Aidan, son of Gabhran, and on his deathbed resigned to him..
