Blessed Pietro Mulucci

Blessed Pietro Mulucci (c. 1257–1347) was a Franciscan friar of the Guelph Mulucci house of Macerata and brother of the city's lord Fredo. In 1320 Pope John XXII made the loyal city a diocese, and on 6 June 1323 named Pietro its second bishop.

In 1325 he attended the canonization inquiry for Nicholas of Tolentino, where witnesses named him as an eyewitness to a miracle. Learned tradition remembers him as a zealous bishop who promoted the cult of Our Lady of Loreto and had a church raised around the Holy House.

In 1320 he had appeared as a witness at an inquisitorial trial of Recanati rebels accused of heresy. He held the see through his family's signoria and its overthrow by the guilds in 1340, dying in office on 29 October 1347.
