GRAZIANO da PISA. – Cardinal, nephew of Eugenius III (1147–53), lived in the 12th century under Pope Alexander III, by whom he was sent in 1169, together with Cardinal Viviano, as a legate of the Holy See to Henry II of England, to negotiate reconciliation with St Thomas of Canterbury.
In 1178 he was elected cardinal deacon of the title of SS. Cosmas and Damian, and in the same year was sent back to Henry II to pronounce the excommunication against the king. Returning to Rome, he followed the exiled Alexander III to Venice and remained an inseparable companion in his peregrinations to the subsequent popes, who entrusted him with various other missions. At the death of Celestine III, the papacy was expected for him, but Innocent III was elected instead; Innocent likewise employed him on a peace mission between Genoa and Pisa. The year of his death is unknown, but it must be placed in the early years of the 13th century (he subscribed to a document in 1205).
