He painted The Allegory of Good and Bad Government in the Sala dei Nove (Salon of Nine or Council Room) in the Palazzo Pubblico (or Town Hall) of Siena.
It includes some twenty scenes basing on two main themes: the Passion of Christ and the Seven Pains of the Virgin, showing Giottesque influences, as well as from Duccio di Buoninsegna and Ambrogio Lorenzetti.
These were not, however, the first paintings with accurate linear perspective, which may be attributed to Ambrogio Lorenzetti (Annunciation, 1344).
