Pietro Azario
Pietro Azario (1312 – after 1367) was a notary born in Novara. By 1347 he was serving the Visconti at Borgomanero, and from about 1362 he acted as chancellor to the podestà of Tortona.
There he compiled his Liber Gestorum in Lombardia, a chronicle of Milan under the Visconti from 1250 to 1362. A copy survives in Milan's Biblioteca Ambrosiana; his death is unrecorded, though he was alive in 1367.
