Maidstone's work still survives in an extract in manuscript, as London, Gray's Inn, MS 14.
[1] Maidstone was elected Bishop of Hereford between 21 August and 30 September 1234[3] and consecrated on 12 November 1234 by Archbishop Edmund Rich at Canterbury.
[4] While bishop, he was sent on a diplomatic mission to Provence as an escort for King Henry III of England's bride.
[4] He had begun to make arrangements to resign the see in May 1237, although a medieval chronicle ascribed the decision to injuries he suffered in 1238.
The Hereford Cathedral records state that he was a friar the same length of time he was a bishop.
