Saint Peter Igneus, also known as Pietro Igneo, was born to a noble family in Florence. He entered the Order of Saint Benedict in 1018 as a monk.
Igneo soon became the abbot for San Salvatore in Fucecchio and he held that position until 1081. In 1072 he was designated as a cardinal and Pope Alexander II named him Cardinal-Bishop of Albano.
He cooperated with Pope Gregory VII to repress simony and reform church discipline. Gregory VII entrusted him with several important missions: in 1079 he served as a papal legate in the German kingdom with the Bishop of Padua to mediate between the Emperor Henry IV and Rudolf of Swabia. Igneo served as a co-consecrator for the episcopal consecration of the new Pope Victor III in 1087. He participated in the conclaves held in 1086 and in 1088.
He is often referred to as a member of the Aldobrandini house but this familiar denomination is not attested in sources as a fact. He died on 11 November 1089.
