Images Trivulzio Cage Cup. Whitish glass with an engraved netting and writing. IV century A.D., found in 1680 at Castellazzo Novarese, Novara

Due to the laborious openwork technique, not many cups have been ordered and executed in the antiquity. Moreover, very few are still undamaged, because of their fragility. Apart from the cup preserved in the museum of Milan, called the “Trivulzio cup”, there is only one other cup that is still undamaged. It belonged to an American family, the Maxwells, and was recently sold to an Arab emir for a large sum. Therefore the Trivulzio cup is the only entire cage cup in Europe at this time.
