Report No. r536

Stephanus Bonaccursius



Alternative Names

Stefano Buonaccorsi



A Florentine born in 1350, Stephanus appears in the college of judges of his native city since c. 1384. The local officials elected him to hold lectures on the Liber Sextus and the Clementines in 1388, but he may have taught already earlier. He never became a canonist of first rank, as is attested by his rather low and stagnant income and the lack of academic writings, despite the fact that he taught for more than forty years. On the other hand, there is considerable evidence of his participation in practical matters, in diplomatic missions and as an author of consilia. He died in 1432/33.
