HELYOT, PIERRE (1660-1716), Franciscan friar and historian, was born at Paris in January 1660, of supposed English ancestry. After spending his youth in study, he entered in his twenty-fourth year the convent of the third order of St Francis, founded at Picpus, near Paris, by his uncle Jer6me Helyot, canon of St Sepulchre. There he took the name of Pere Hippolyte. Two journeys to Rome on monastic business afforded him the opportunity of travelling over most of Italy; and after his final return he saw much of France, while acting as secretary to various provincials of his order there. Both in Italy and France he was engaged in collecting materials for his great work, which occupied him about twenty-five years, L'Histoire des ordres monastiques, religieux, et militaires, et des congregations sSculieres, de I'un et de I'autre sexe, qui ont ete elablies jusqu'a present, published in 8 volumes in 1714-1721. Helyot died on the sth of January 1716, before the fifth volume appeared, but his friend Maximilien Bullot completed the edition. Helyot's only other noteworthy work is Le Chretien mourant (1695)
The Histoire is a work of first importance, being the great repertory of information for the general history of the religious orders up to the end of the 17th century. It is profusely illustrated by large plates 1 Irish Parl. Debates, i. 309, 310.
2 It is generally supposed that the title conferred by this patent was that of Viscount Suirdale, and such is the courtesy title by which the heir apparent of the earls of Donoughmore is usually styled. This, however, appears to be an error. In all the three creations (barony 1783, viscountcy 1797, earldom 1800) the title is " Donoughmore of Knocklofty." In 1821 the 1st earl was further created Viscount Hutchinson of Knocklofty in the peerage of the United Kingdom. The courtesy title of the earl's eldest son should, therefore, apparently be either " Viscount Hutchinson " or " Viscount Knocklofty." See G. E. C. Complete Peerage (London, 1890).

The material has been arranged in dictionary form in Migne's Encyclopedic theologique, under the title "Dictionnaire des orders religieux " (4 vols., 1858).
