IVES, or Yves (St), a celebrated bishop of Chartres, born in the territory of Beauvais in the 11th century. His merit procured his election to the see of Chartres in 1092, or 1093, under the pontificate of Urban II. who had deposed Geoffroy his predecessor for sundry accusations against him. Ives particularly signalized himself by his zeal against Philip I. who had put away his wife Bertha of Holland, and had taken Bertrade of Montfort, wife of Fouques count of Anjou. Afterward he devoted himself wholly to the functions of his ministry; made several religious foundations; and died in 1115. Pope Pius V. permitted the monks of the congregation of Lateran to celebrate the festival of St Ives on the 20th of May. We have a collection of decrees of his compiling, Exceptiones ecclesiasticarum regularum, a Chronicon, and 22 sermons; all very valuable pieces, which were collected and published in one volume folio in 1647, by John Baptist Souciot, canon of Chartres.
