The vita of Columba is also the source of the first known reference to the Loch Ness Monster. According to Adomnan, Columba came across a group of Picts who were burying a man killed by the monster, and saved a swimmer with the sign of the Cross and the imprecation "You will go no further", at which the beast fled terrified, to the amazement of the assembled Picts who glorified Columba's God. Whether or not this incident is true, Adomnan's text specifically states that the monster was swimming in the River Ness -- the river flowing through the loch -- rather than in Loch Ness itself.
