‘In the fourth and fifth century it was the habit to ornament the bottoms of bowls and cups with designs in gold, either fixed to the surface or enclosed between two layers of glass. These specimens have generally been found in the Catacombs of Rome; but two or three have been found at Cologne, one of which is in the collection. It is the remains of a disc of considerable size, with a central design, now destroyed; around are eight compartments, with subjects from the Old and New Testaments: Moses striking the Rock, the History of Jonah, Daniel in the Lions’ Den, the Fiery Furnace, the Sacrifice of Isaac, the Nativity, and the Paralytic Man; of these, the Nativity is a very rare representation. ‘Of glass of a Teutonic origin there is but one specimen in the collection, a tumbler of peculiar form, from a cemetery at Selzen, in Rhenish Hesse. Like other glasses of the time, it is so made that it cannot be put down until it has been emptied, and thus testifies to the convivial habits of the Teutons. ‘Of early Byzantine glass but little is known; the bowl with Diana and Actæon, already noticed, is very probably of that period; and a Byzantine cameo with the head of CHRIST should be mentioned. ‘Of glass of the middle ages, from the West of Europe, but little or nothing has been preserved save the exquisite painted glass in cathedrals and churches. Of the Eastern glass of the same period several specimens are in the collection. Among these is a very beautiful bottle, probably of the thirteenth century, decorated with a minute pattern of birds; a lamp of large size, made in Syria to hang in a mosque, bears the name of SHEIKHOO, a man of great wealth and importance in Egypt and Syria, who died in 1356, after building a mosque at Cairo. ‘To a later period of the Eastern glass works may be referred an ewer of a sapphire blue, resplendent with gold arabesques, and several other richly decorated pieces, all made in Persia.
