He was named as one of the counsellors to assist the queen, but, fearing to incur the king's displeasure and using his favourite phrase ira principis mors est, he gave her very little help; and he signed the letter to Clement VII.
Some doubt exists concerning Geoffrey's share in the compilation of the Vita et mors Edwardi II., usually attributed to Sir Thomas de la More, or Moor, and printed by Camden in his Anglica scripta.
Recent scholarship, however, asserts that More was no writer, and that the Vita et mors is an extract from Geoffrey's Chronicon, and was attributed to More, who was the author's patron.
In the main this conclusion substantiates the verdict of Stubbs, who has published the Vita et mors in his Chronicles of the reigns of Edward I.
