Byzantine art is a debased form of the classic, but with a large mixture of Greek; not of the old classic Greek type which had long been exhausted, but of that Asiatic Greek which derived so much of its splendour from the rich but unimaginative decorations of Persia. The objects actually executed at Constantinople or by Byzantine artists now remaining can scarcely be included in a treatise on furniture. They are mostly caskets and other small pieces executed in metal or in ivory. Accounts of many interesting pieces of Byzantine sculpture will be found in the "Description of the ivories in the South Kensington museum." Amongst them the diptychs of the consuls are not only the most important, but the most interesting to a treatise on furniture, as we see in them consular seats and thrones of many varieties.
We may select amongst other examples the following, which can be studied in the museum or referred to in that work. For instance, n^{ o.} 368 (fully described in Mr. Maskell's "Ivories") is one leaf of a consular diptych of Anastasius Paulus Probus Sabinianus Pompeius. The consul is represented seated on a chair of very ornate character. It is like the old folding curule chairs of Rome, but with elements both of Greek and Egyptian ornamentation, such as belong to the massive marble seats, supported by lions or leopards, with the heads sculptured above the upper joint of the hind legs. In the mouths of these lions' heads are rings for the purpose of carrying the chair, and the top frame is ornamented with little panels and medallions containing winged masks and portrait heads of the consul and his family or of members of the imperial family. On each side of the seat are small winged figures of Victory standing on globes and holding circular tablets over their heads. These probably represent the front of the arms, and are supposed to have a bar stretching from the heads or the circular tablets to the back of the seat. This feature too is a continuation of types that are to be found on Greek vases and in the chairs of both Nineveh and Egypt. A low footstool with an embroidered cushion on it is under the feet of the consul, and another cushion, also embroidered, covers the seat. This represents a chair of the sixth century.
