Aedan mac Gabrain was King of Dal Riada in south-western Scotland. He was probably born about 550 and became king in 574. He named his firstborn son Arthur (Artorius), probably after the great Arthur, the overking who had recently died.
According to the Life of Columba, Aedan was unsure which of his three sons—
Arthur, Eochaid Find, or Domingart—would be his successor. St. Columba chillingly prophesied that “none of these three shall be king, for they shall fall in battle, slain by their enemies; if you have any younger sons let them come to me, and the one the Lord has chosen will at once rush into my lap.” Fortunately, Aedan did have more sons. It was Eochaid Buide who ran straight to Columba.
Arthur and Eochaid Find were killed shortly afterward in the Battle of the Miathi in about 575-80. Domingart was defeated and killed in battle in “Saxonia,” which was presumably what is now eastern England. Eochaid Buide did indeed become king, 608-29. Aedan himself lived on until 609.
AEDUI
A Gaulish tribe, with its main center at Bibracte. According to the Roman historian Livy, the Aedui joined the expedition of Bellovesus into Italy in the sixth century BC. Around 90 BC they became allies of Rome. When they were invaded and defeated by their neighbors the Sequani, they sent Diviciacus the Druid to Rome to appeal to the senate on their behalf
When Julius Caesar arrived in Gaul in 58 BC, he restored their independence. Even so, the Aedui joined the coalition of Gaulish tribes against Caesar. After Vercingetorix surrendered at Alesia, however, they were glad to go back to supporting Rome. Augustus ordered Bibracte, their native capital on Mont Beuvray, destroyed; it was replaced by a new town, Augustodunum (Autun).
