Gui the institutor of the order of the Hospitallers of the Saint-Esprit de Montpellier, seems, in 1197, to have united several religious persons, and to have written down the rules of that new institution, which was recognised and confirmed by a bull of pope Innocent III, April 23,1198. This pontiff called Gui, with several of his co-workers, to Rome, where he charged them with the administration of the hospital of St. Mary in Saxony, The order founded by Gui had for its special object to offer hospitality to the sick, and was regarded as a military order. Gui died in 1208. See Hoefer, Nouv. Biog. Generale, s.v.
