Authority: — The Aberdeen Breviary.] Fergus, an Irish bishop, came to the west of Scotland, and after founding three churches near Strogeth, went on into Caithness, where he founded churches at Wick and Halkirk. After that he visited Buchan, and built a church at Lungley. Then he went on to Glamis, and there he died. At Glamis is S. Fergus' cave and S. Fergus’ well. At a council held in Rome in 721, under Gregory II., there were present Fergustus of Scotland,1 and “ Sedulius, bishop of Britain, of the Scottish race.” Sedulius must have been bishop of the Strathclyde Britons, who submitted to the Pope in 703. North Wales submitted in 768, South Wales in 777. The name was probably Siedhuil or Shiel. Fergustus is probably S. Fergus Cruithneach, commemorated in the Donegal and Tallaght Martyrologies on September 8. Fergus, who died at Glamis, is said by the Aberdeen Breviary to have been formerly a bishop in Ireland, and so these two are probably the same.
