bonino da campione sculpted the equestrian statue of bernabò visconti for the church of san giovanni in conca around 1363. its positioning near the church's main altar was regarded as highly problematic by contemporaries and it was commented on by poet and intellectual petrarch among others. the equestrian statue was reused – with changes and additions carried out by the same bonino in 1385-86 – as bernabò's funerary monument in the same church. it is now preserved in the castello sforzesco in milan.an erratic small-size male head in marble now in the storerooms of castello sforzesco has recently been rediscovered and tentatively identified as a portrait of the elderly bernabò. this work too has been attributed to bonino da campione.
