Source-derived summary

Giovanni Stefano Ferrero (1474–1510) (called the Cardinal of Bologna) was an Italian Roman Catholic bishop and cardinal.

Biography

Giovanni Stefano Ferrero was born in Biella on 5 May 1474, the son of Sebastiano Ferrero and Tomena Avogadro. The Ferrero family was allied with the Acciaioli family, one of the most prominent families in the Republic of Florence. Gianstefano Ferrero's younger brother Bonifacio Ferrero also became a cardinal.

Ferrero studied canon law at the University of Padua. He then moved to Rome and became an Auditor of the Roman Rota. He next became a protonotary apostolic.

At the insistence of Blanche of Montferrat (regent for her son Duke Charles II of Savoy), Ferrero was named coadjutor bishop of Vercelli on 24 April 1493. He succeeded as Bishop of Vercelli on 16 July 1499, occupying the see until 21 January 1502. He occupied the see again from 31 October 1503 until 5 November 1509, when he exchanged it with his brother Bonifacio Ferrero.

Editorial analysis

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
