James of Viterbo
Italian archbishop

James of Viterbo (Italian: Giacomo da Viterbo; c. 1255 – c. 1307), born Giacomo Capocci (nicknamed Doctor speculativus), was an Italian Roman Catholic Augustinian friar and Scholastic theologian, who later became Archbishop of Naples.
Life
James was born Giacomo Capocci in Viterbo in the Papal States around the year 1255. Little information is available regarding his early years. He joined the Order of St. Augustine around the year 1272 at the monastery of the Most Holy Trinity in Viterbo. He was then sent to pursue theological studies at the Order's General House of Studies in Paris, where he studied under Giles of Rome.
Capocci is first mentioned in the surviving historical records in the year 1283 in the capitular acts of the Augustinians’ Roman province as a recently appointed lecturer in the Convent of Viterbo, meaning that he must have spent at least five years at the University of Paris, because the Augustinian Order required its lecturers to be trained in Theology in that city for a duration of five years. Giacomo returned to Paris for further studies, as his name is again mentioned in the capitular acts in 1288, where he is said to hold a Bachelor of Theology degree from the University of Paris.
Capocci received his Master of Theology degree in 1293, and taught in Paris for the next seven years, during which time his output was extensive as all of his works in the fields of speculative theology and metaphysics date from this time. In 1299 he became the Order's Regent of Studies.
This brief starts where responsible research should: with the source description of “James of Viterbo” as italian archbishop. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as italian archbishop. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q352625. VIAF identifies the subject as 288753976. The Library of Congress control number is nr94037138. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1255, 1307, 1272 and 1283.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
