Gauzlin a French prelate, natural son of Hugh Capet, became abbot of Fleury after the death of Abbon in 1005. He sent to Brittany the monk Felix to reform the monasteries. At the death of Dagbert, bishop of Bourges, in 1020, he was raised to the dignity of prelate in this vacancy; but the opposition of the inhabitants hindered him for a long time from taking possession of 'his see, and only through the intervention of the pope, Benedict VIII, he entered upon these duties in 1014. In 1022 he was at the Council of Orleans, which condemned the heresiarch Stephen, and in 1024 at the Council of Paris, where he debated the question of the apostleship of St. Martial. He died in 1030. See Hoefer, Nouv. Biog. Generale, s.v.
