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

The cage cup, called also ‘diatreton cup’ is an ancient roman vessel carved in a single piece of glass and decorated by undercutting so that the surface decoration stands free from the body of the glass, supported only by struts. It was found in the XVII century in a sarcophagus near the city of Novara. In the XVIII century abbot Trivulzio acquired it from the city of Novara - that is why the cup is also called the Trivulzio cage cup. The cup raised so much interest in the citizens of Milan, that they decided to buy it in 1935, by means of a common public signing, from the Trivulzio family and now it belongs to the civic Milanese collections.
