Thomas Maria Mamachi
italo-Greek Dominican theologian and historian
Thomas Maria Mamachi (December 4, 1713 in Chios – June 7, 1792 in Corneto, near Montefiascone), was an Italian-Greek Dominican theologian and historian.
Life
At the age of sixteen, he entered the convent of Chios and passed later to St. Mark's at Florence and the Minerva at Rome.
In 1740, he was appointed professor of physics in the Roman Sapienza university, and in 1743, he taught philosophy at the Propaganda Fide. His residence at Florence and Rome brought him into contact with brilliant men of his order, e.g. Giuseppe Agostino Orsi, Divelli and Daniello Concina, and greatly facilitated his progress in his studies. He collaborated with Orsi in his "De Romani pontificis in synodos oecumenicas et earum canones potestate".
Soon, Pope Benedict XIV appointed him prefect of the Casanatensian Library, master of theology and consultor of the Congregation of the Index. Owing to his office he had to take part in the controversy between the Appellants (Jansenists) and the Jesuits, and displayed an impartiality which greatly increased the difficulties of his anxious and laborious position. He engaged in lively theological controversies with Gian Domenico Mansi and Cadonici.

Why this record matters
“Thomas Maria Mamachi” is worth following because a concise public description often conceals a longer documentary argument. Here, Thomas, Maria and Mamachi provides the most credible route into that argument.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q3524840. VIAF identifies the subject as 12299733. The Library of Congress control number is n85050258. 3 of 4 selected statements include explicit references; 0 carry qualifiers and 1 use preferred rank. The first chronological checks are 1713, 1792, 1740 and 1743.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. 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.
