There the Antipope Benedict XIII authorized Colette's program of reform and appointed de Beaume as her guide and spiritual assistant in this.
[3] Several attempts at founding a community of nuns which would follow the original Rule of St. Clare were made in the County of Burgundy, with one finally taking root successfully in Besançon.
Abbess Colette made the decision to have his body buried in the chapter room of the monastery rather than in its chapel, not only out of her attachment to her longtime guide and support, but also to avoid the possibility of crowds being drawn to the tomb of a widely noted holy figure, which would have been disruptive to their lives.
De Beaume wrote many letters and a range of spiritual treatises for the Colettine nuns, as well as a Rule for the Coletan friars.
Among De Beaume's other writings is one on "Theologia Mystica", which had been mistakenly attributed to Saint Bonaventure, making him one of several Pseudo-Bonaventuran authors.
