 Early in the twelfth century there was at Würzburg an ecclesiastic and teacher known as David.His surname Scotus shows that he was probably a Gael from either Ireland or Scotland, if he is identical with the homonymous Bishop of Bangor, from Wales (see below).According to Ekkehard's "Chronicon", Emperor Henry V received him, was charmed with his virtue and knowledge, and made him one of the imperial chaplains.
