Guillaume de Deguileville
According to the second redaction of the "Vie", Guillaume was thirty-six years old when he wrote his first redaction in 1330, so he must have been born ca. 1294. The "Âme" was written immediately after the second redaction of the "Vie" (1355), and in it he states that he was over 60 years old when writing the "Âme". He also refers to a passage in the "Vie" which only occurs in the second redaction of the poem, which is another indication that he wrote the "Âme" after 1355. Guillaume wrote this second redaction of the "Vie", he states in its prologue, because the first redaction had been stolen. This does not mean that this first redaction was lost to posterity, for, according to Clubb in the introduction of his edition of Egerton 615, J. J. Stürzinger based his edition of "Vie" on it.
