Stephen's official hagiography, written by Bishop Hartvic and sanctioned by Pope Innocent III, narrates that he "was fully instructed in the knowledge of the grammatical art" in his childhood. This implies that he studied Latin, though some scepticism is warranted as few kings of this era were able to write. His two other late 11th-century hagiographies do not mention any grammatical studies, stating only that he "was brought up by receiving an education appropriate for a little prince". Kristó says that the latter remark only refers to Stephen's physical training, including his participation in hunts and military actions. According to the "Illuminated Chronicle", one of his tutors was a Count Deodatus from Italy, who later founded a monastery in Tata.
