Due to confusion with other authors called David and due to an abundant body of medieval legend, almost nothing is known with certainty about the historical David. Armenian tradition makes him a native of Taron, but this is not substantiated in contemporary sources and may be due to conflation with another person.Valentina Calzolari: David et la tradition arménienne.
