It is clear ... that he composed the second recension in 1355, that he had then been a monk for thirty-nine years and that he had entered the monastery at Chaalis in 1316 at the age of twenty-one or twenty-two. He was of Norman origin; his family was from the village of Digulleville, near Beaumont-Hague in Manche ... Since the date 1358 is mentioned in Le pèlerinage de Jhesuchrist, Deguileville lived until he was at least sixty-four")
