Giovanni d'Andrea, ca. 1270-1348


Also known as Johannes Andreae, Iohannes Andreae Bononiensis, Johannes de Anania, Jean d'Andrea, Johannes Andree, Jean André, and Giovanni d'Anangi.

One of the most celebrated canonists in medieval Europe, Giovanni d'Andrea was born c. 1270 in Italy. He studied Roman law in Bologna under Martinus Sillimanus and Riccardus Malumbra, and canon law under Egidius Fuscarariis and the the equally renowned Guido de Baysio (d. 1313).  With the exception of two stays in Padua (1307-1309 and 1319), Giovanni d'Andrea taught law at the University of Bologna until his death in 1348.  In addition to his numerous works, d'Andrea taught several students, who in turn became leading canonists during the fourteenth century, including Giovanni Calderini (d. 1365), Paulus de Liazariis (d. 1356), and Johannes de Sancto Georgio (1320-1378).

Affectionately known as iuris canonici fons et tuba by his contemporaries, d'Andrea became friends with early humanists in Italy. Both Cino da Pistoia (1270?-1336/1337) and Francesco Petrarch (1304-1374) were his friends. Despite his fame in canon law, Giovanni d'Andrea never sought a career in the Church, remaining a layman, marrying, and having children.

D'Andrea's gloss commentaries on the Decretales, Liber Sextum, and Clementinas became standards reference works and sources for study in the later Middle Ages, with his glosses on the Liber Sextum and Clementinas becoming the the text used as the standard Glossa Ordinaria for the respective works. He died in Bologna in 1348, one of the many victims of the Black Death. His exquisitely decorated Gothic tomb can be found in the Museo Civico di Bologna.

Giovanni d'Andrea and Manuscripts in Spain

The Bio-Bibliographical Guide to Medieval and Early Modern Jurists has created an inventory of manuscripts and early printed editions of Giovanni d'Andrea's works in Europe. The Guide identifies thirty titles with Giovanni d'Andrea, several of which have only one extant manuscript.

The Giovanni d'Andrea Mapping Law in Medieval Spain Project has helped identify several new manuscripts not found in the Guide's database. Re-cataloging HMML's microfilm collection of Spanish manuscripts has thus allowed us to expand our knowledge of the transmission of this important canonist's works, not only in Spain, but also in Europe.


Crucial here is the knowlege of Gionvanni d'Andrea's important influence on canon law in Catalunya, where the legal scholarship associated with the Cathedral of Seu d'Urgell became an important center of dissemination in Spain. Similarly, one can see how the Cathedrals of Tarazona and Huesca in Aragón too acquired several copies of his works, while the Cathedral of Toledo contained twenty-four manuscripts of d'Andrea's works.
