Pope Celestine III (1191-1198): diplomat and pastor

Hyacinth Bobone (c. 1105?1198) was one of the great figures of twelfth-century Europe.

Active in the Roman Curia from the 1120s, a student in Paris, and associated with both Peter Abelard and Arnold of Brescia, he was made cardinal deacon of Santa Maria in Cosmedin in 1144 and served there during forty-seven years before being elected as pope in 1191.
