Andrew of Fleury was a Christian monk and contemporary historian of the Peace and Truce of God movements.
Andrew's chief work was Miracula sancti Benedicti ("The Miracles of Saint Benedict"), written c.1043.
[2] He records the presence, on the Christian side, of four counts: Raymond Borell of Barcelona, Bernard I of Besalú, Wifred II of Cerdagne, and Ermengol I of Urgell.
[3] He reports that Gauzlin mistakenly believed that the "heretics of Orléans" nuptias non prohibeo, secunda matrimonio non dampno ("they do not prohibit weddings, according to which they do not damn marriage"); Andrew more accurately reports that nuptias con benedictione non debere fieri, sed accipiat quiscumque qualiter voluerit ("weddings with a blessing they forbid to be made, rather they consider as indebted whomever wills it").
[4] Andrew also includes a copy of the letter Gauzlin addressed to Robert II of France in 1022, after the king asked him why blood had been seen to fall from the sky.
