Peter I (bishop of León)

Peter I (Spanish Pedro) was the bishop of León from about 1087 until his deposition around 1111.

During his episcopate, the city of León declined in importance relative to the city of Toledo. Peter had to contend with the claim of the archbishops of Toledo that the diocese of León lay within their province, a claim approved by Pope Urban II in 1099. In 1104, Peter successfully convinced Urban's successor, Paschal II, to grant León an exemption from metropolitan control on the basis of a forged document, the so-called Division of Wamba. Significantly, the dioceses of León and Oviedo had common interests at this time. The only copies of the Division that support the Leonese claims emanate from the scriptorium of the cathedral of Oviedo under Bishop Pelagius, a notorious forger. The original of the papal bull of exemption still survives in the cathedral of León.

When Duke Raymond of Galicia died on 20 September 1107 in his castle of Grajal in the diocese of León, Bishop Peter gave permission for his body to be brought back to Santiago de Compostela for burial.

Peter I (archbishop of Lyon)

Peter (died 25 December 1139) was a Benedictine monk and a "prelate of more than average distinction", who held the bishopric of Viviers (1125–31, as Peter I) and subsequently the archbishopric of Lyon (1131–39, as Peter I). Throughout his archiepiscopate he held the office of Papal legate.

Prior to his election to Viviers, Peter was a monk of Cluny. There he first met and befriended Peter the Venerable, later abbot. He once gave Peter a golden ring as a sign of his affection.

In 1138 the election of the bishop of Langres was disputed between two factions, and in June or July Peter gave his approval to the election of a Cluniac bishop—probably William of Sabran—whom he duly consecrated. Although Bernard of Clairvaux attacked Peter in a letter to Pope Innocent II on this occasion, it does not seem to have harmed Peter's reputation.

In 1139 Pope Innocent sent him as legate to the Kingdom of Jerusalem to settle a dispute between Patriarch Ralph of Domfront and the canons of the Antioch. Peter sailed to Acre and went from there to Jerusalem. He returned to Acre and died there before moving on to Antioch. William of Tyre, who calls him "a man of a venerable life, simple and God-fearing, but old and now verging on senility" in his chronicle, raises the spectre of poisoning. His obituary written at the priory of Leigneux dates his death incorrectly to 31 May.
