ABSTRACT
In 1590 the Holy Roman Emperor Rudolf II commissioned a small stone cameo from the Milanese gem-cutter Alessandro Masnago (Figure 19.1).1 Measuring only 3.3 cm by 4 cm, it was set in a gold frame with coloured enamelling by Jan Vermeyern in Vienna in about 1602. From the testimony of subsequent inventories it appears to have ended up in Rudolf’s famous Kunstkammer in Prague.2 Documentary evidence can reveal little more, so we must turn to the cameo. As all agate, it would have started life as a grey lump of stone and, when cracked open, exposed the colourful chalcedony of its interior. Through trading, it eventually ended up on the worktable of Masnago, where the inner parts of the oval were worked down to the ochre layer and the white vein was picked out into tiny faces and clouds. Eventually the religious image emerged from the stone. Mary and Jesus stare out brightly, encircled by an inner band of clouds. The uppermost pink-red surface was kept around the edge as a frame and crafted into billowing clouds containing angels’ faces flanked by wings. The miniature image is not clearly defined but works intricately with the natural flow of colours in the stone. Its size and complexity make the viewer strain and engage to look into the stone to see the vision.
