Figs. 5, 6, 7, 8. Are specimens in
the British Museum of the delicate and beautiful mosaic pictures
worn, probably, as rings or brooches, when mounted in gold, by the
Fig. 9. The formation of this pattern
differs from the mosaic; and it is somewhat difficult to imagine the
manipulations of the Glass-maker in working out its peculiar design.
Fig. 10. Curious specimen of ancient cased
Glass, of the same class as the Portland vase, also from the British
ANCIENT VENETIAN SPECIMENS.
Fig. 1. Ancient Venetian cup and cover,
called Vitro di Trino. This specimen was purchased about the year
1836, at the sale of the collection of Lady Bagot. The position of the
entrapped air-bubbles varies, when the mass is stretched out of its
original structure, they are upon the diamond crossings of the white
enamel threads, as fig. 3; although, usually, between the junction of
the angles, as fig. 4. The foot is made by a ring neatly cast upon the
bottom of the cup, within which all the white enamel lines concentrate
to the centre, with the accuracy of lathe or engine turning.
Fig. 2. Ancient Venetian frosted vase;
formerly the property of Lady Bagot, subsequently of the author.
The satyr heads have been impressed by a seal or die, after the vase was
frosted, the gilding of which, as well as the border or rim, has been
fixed by burning. The frosting manipulation and the Vitro di Trino are
explained at pages 113
