BONACCORSO DA BOLOGNA

BONACCORSO da Bologna. — Theologian, born at the beginning of the 13th century in Bologna, where he entered the Dominican Order and completed his theological studies. Around 1230 he set out as a missionary for Greece. For 45 years he devoted himself to the conversion of dissidents. To this end he wrote in Greek and Latin the *Thesaurus veritatis fidei*, a collection of sentences from the Holy Fathers, directed particularly to refuting the various errors of the Greeks. He died in Greece in 1275. His work, which remained unknown, was discovered in the Dominican convent on Euboea by Friar Andrea Doto, who presented it to Pope John XXII in 1327. Of the *Thesaurus*, published only in part by Reuch, two manuscripts are preserved in Paris (Bibliothèque Nationale 1251 and 1252) and one in Milan (Biblioteca Ambrosiana D 78 sup.).
