He was born in the village of Rosate (Rosciate) in the district of Bergamo, and was of humble parentage.
He studied law under Oldradus de Ponte and Rizzardo Malombra at the University of Padua,[1] where he gained the degree of Doctor, without, however, becoming a teacher.
Albericus also studied under Ranieri di Forlì and had contact with Bartolus de Saxoferrato.
In 1331 and 1333 he was involved in reforming Bergamo's civil statutes, and he was sent several times (in 1335, 1337–38 and 1340–41) as ambassador to Pope Benedict XII's court at Avignon.
Special mention should be made of his commentaries on the Digests and the Codex, which were often printed later, as at Lyon (1517, 1545–48); the "Opus Statutorum" (Como 1477; Milan, 1511); and the Dictionarium, a collection of maxims of law as well as a dictionary, which was often reprinted.
