Fabio Cioni
Italian notary and Protestant dissenter

Fabio Cioni (c. 1520 – unknown) was an Italian notary from Grosseto who became involved in Protestant reformist circles in mid-16th-century Tuscany. He was later investigated by the Roman Inquisition for heresy and condemned to life imprisonment on the galleys of the Grand Duchy of Tuscany after his conviction in 1569.
Early life and education
Cioni was born in Grosseto into a modest family of merchants described in contemporary sources as persone honorate. He studied notarial law in Siena at the university-associated school of notaries. After completing his studies, he returned to Grosseto, where he worked for a time as an elementary schoolteacher before qualifying as a public notary.
Surviving records from the State Archives of Siena document his activity as a notary between 1562 and 1568.
Religious beliefs and reformist activity
Around 1544, Cioni entered the intellectual circle of the Sienese physician Achille Benvoglienti. Within this group he encountered reformist ideas associated with Protestant theology, including doctrines derived from Calvinist and earlier Italian evangelical reform currents. The group discussed works such as John Calvin's Institutes of the Christian Religion and held heterodox views on justification by faith, the Eucharist, purgatory, and the cult of saints.

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 28, 2026. The linked authority identifier is Q98625678. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1520, 1569, 1562 and 1568.
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.
