'''William Perault''' (c. 1190 – 1271), also spelled '''Perauld'''; Latinized '''Peraldus''' or '''Peraltus''', was a Dominican writer and preacher.

==Life==
He was born at [Peyraud](/source/Peyraud), [France](/source/France). He studied at the [Sorbonne University of Paris](/source/Coll%C3%A8ge_de_Sorbonne), and there, being drawn to the religious life by the preaching perhaps of [Jordan of Saxony](/source/Jordan_of_Saxony), he was received into the [Dominican Order](/source/Dominican_Order).

It is thought that Perault was somewhat advanced in years when he embraced the religious state, although the precise date of his entrance into it is also unknown. He entered the order at [Paris](/source/Paris), but was destined, according to a custom then existing, for the convent at [Lyon](/source/Lyon)s. At Lyons, where he passed his life, at once contemplative and active, he rendered service to the Church by the brilliancy of his writings and preaching and by the charm and splendour of his virtues.

His part in ecclesiastical affairs was for a time also very important. For fully ten years he performed all the episcopal functions of the Church of Lyons, having been chosen for this work during the vacancy of the [see](/source/episcopal_see) by [Philip I, Count of Savoy](/source/Philip_I%2C_Count_of_Savoy) who, although not in Holy orders, bore the title of [Archbishop of Lyon](/source/Archbishop_of_Lyon) from 1245 to 1267. Because of Perault's long labours in ministering to the needs of the [diocese](/source/diocese), he himself came to be known as the Bishop or Archbishop of Lyon. This error was further emphasized by the title of bishop which a later hand added to many of his writings. Authors such as [Gerson](/source/Jean_Gerson), [Noël Alexandre](/source/No%C3%ABl_Alexandre), [Jacques Échard](/source/Jacques_%C3%89chard), and [Hurter](/source/Hurter) say that William Perault was never Archbishop of Lyons, as the {{lang|la|[Gallia christiana](/source/Gallia_christiana)}} asserts, [Louis Ellies du Pin](/source/Louis_Ellies_du_Pin) is not justified in saying that he was never more than a religious of the Order of Preachers (cf. [Antoine Touron](/source/Antoine_Touron), {{lang|fr|Hist. des hommes illust.,}} 1, l.2, 184).

He died at Lyons.

==Writings==
