John Bromyard

There is evidence in his works that he had served in the diocese of Llandaff in South Wales, and he shows familiarity with customs and circumstances in France and Italy.

The Dominicans had been fighting for a foothold here for eighty years against the resistance of the Dean and Chapter, before they were finally established under the patronage of Edward II in 1322.

The sheer volume of his work suggests that it may well have been produced by a collaborative process involving the other friars at the Hereford priory, with Bromyard acting as editor in chief.

He uses "scientific knowledge" (natura ratione) to explain natural phenomenon such as "rain" taking away the mysticism of "acts of God".

He was particularly fond of Canon law, devoting the Tractatus iuris to expounding Christian doctrine and morality almost exclusively by means of citations from legal texts.
