Antonio Fatati was born in
Ancona in the
Papal States circa 1410 to the
nobles Simone Fatati and Buzia dei Lavaroni; he came from a line of municipal officials. His two brothers were Marino and Iacopo. Fatati studied in
Bologna before his
ordination to the
priesthood. Bishop Astorgio Agnesi appointed him as a
canon and
archpriest for the San Ciriaco cathedral on 5 November 1431 while he served as the
vicar general for
Ragusa from 1440 to October 1441 to replace Archbishop Antonio Venieri (his sister-in-law's uncle).
Pope Eugene IV appointed him as an
abbot for the San Pietro al Conero
convent in 1440.
Pope Nicholas V also held Fatati in high esteem and appointed him a canon of the chapter of
Saint Peter's Basilica on 4 June 1447 while giving him other important positions in the
Papal States. The pope also made him a
cleric in the
Apostolic Camera in 1449. The
King of Naples Alfonso V of Aragon became impressed with Fatati and made him one of his councilors in 1456. He received his appointment from Pope Nicholas V as the
Bishop for Teramo on 6 November 1450 but was forced to reside in
Macerata given his other duties in service to the Papal States. He did not believe he could run a diocese when he learnt about his appointment due to his several other important positions that confined him to Macerata instead. Fatati also convoked a
diocesan synod on 11 March 1459 which the new
Pope Pius II appreciated due to Fatati's desire for diocesan reform and renewal. His tenure lasted until 1460 when Pope Pius II made him an
assistant bishop for
Siena to help his
nephew Cardinal Francesco Todeschini Piccolomini (the future Pope Pius III). The pope was impressed with Fatati's management that he appointed him as the
Bishop for Ancona e Unama on 3 November 1463 (he held this position until his death). Fatati accompanied Pius II to the
Mantua Congress in 1459 while hosting the pope in his diocese; the pope died there in 1464 in the middle of planning a
crusade against the
Ottoman Turks.
Pope Paul II also was impressed with his abilities and named him as the
treasurer for
Bologna for the 1466 to 1470 period while his successor
Pope Sixtus IV also valued his management and diocesan organization. Fatati died in his diocese on 9 January 1484; his remains were interred in the diocesan cathedral. His remains were found
incorrupt after their
exhumation in 1529 while a new
sarcophagus was commissioned in 1795. ==Beatification==
