The metal work of the Byzantine period - from the fourth to the eleventh century - is characterized by a subservience of the design to the material employed; in other words, what was lacking in good drawing and modelling was replaced by splendour and magnificence in the general effect.

The Use Of Gold With Enamels

The Use Of Gold With Enamels was a great feature in Byzantine art and throughout the Middle Ages. When the great Church of Santa Sophia was rebuilt by Justinian in the sixth century, the best artists were employed to make the great altar screen, and to decorate the sanctuary in resplendent works in gold, silver, and enamels. The altar was made in marble plated with gold in which was set precious stones and crusted enamels. It was supported by pillars thickly plated with gold The canopy or ciborium of the altar rested on four silver-gilt columns, and this canopy was overlaid with plates of silver, on which were figures wrought in niello work. The canopy had an orb surmounted by a cross made of gold and inlaid with large precious stones. The screen in front of the altar had its dado or lower part of gilt bronze, and the pillars and architrave silver-plated. It had also statues and panels of silver, the latter being engraved with figures of saints in niello work. The ambo or pulpit had a canopy of plated gold set with precious stones. The sanctuary of Santa Sophia contained forty thousand pounds weight of silver, and the altar vessels were made of gold set with stones of the greatest value.

The above description is given by Mr, J. Hungerford Pollen, in his handbook of "Gold and Silver," to whom we are indebted for many of the illustrations and some interesting information on the subject of the precious metals.

It will be seen from this that Justinian had established a great school of goldsmiths and enamellers at Byzantium, and when Leo the Iconoclast in the eighth century, and Theophilus in 832, finally drove out the image-makers and many other goldsmiths from Constantinople - checking in a great degree the art of the metal-worker in the Eastern Empire - they were received with great welcome in Italy, Germany, and France, where they followed the practice of their art under more favourable auspices.

Under Basil the Macedonian, who died in 886, the images were restored, and a great encouragement given to all kinds of art; and during the reign of Constantine, his grandson (912-959), Constantinople was again a great art centre from which Italy and Germany procured their chief artists. The celebrated Pala d'Oro, or Altar of St. Mark's, Venice, and the bronze gates of San Paolo, near Rome, were made in Constantinople.

The splendour and treasures of the imperial city remained intact until its capture by the French and Venetians in 1204, when a general sacking of nearly all of its treasures took place.

The Byzantine Style Of The Scroll-Work And Acanthus

The Byzantine Style Of The Scroll-Work And Acanthus was of the Greek type, and was admirably suited to show to advantage the rich quality of the precious metals, and a modified character of this leafage appears in the Romanesque metal work. The vine-leaf, grapes, and twisting tendrils were first used in a symbolic sense in the Byzantine style and subsequently in the Romanesque. The acanthus and the vine are treated very much alike in the conventional ornament of the latter style, which is really a connecting-link between the Early Gothic foliage and the Byzantine. This may be seen in the illustration (Fig. 133) of a portion of the base of the great candlestick at Milan, a work of the twelfth century.

A celebrated "find," known as the "treasure of Petrossa," was brought to light in 1837 by some peasants who were digging on the banks of Argish River, a tributary of the Danube. It consists of vessels of pure gold, vessels made of slices of garnet and other stones, a torque or collar of gold, a great dish, and some brooches of a large size. They have all been inlaid with precious stones, and have simple but well-designed ornaments. The workmanship is Byzantine, or it may have been done by Gothic artists after Byzantine models.

This treasure is now in the museum at Bucharest. The influence of the Byzantine school of metal workers spread, not only over the continent of Europe, but as far as England and Ireland; and many portable altars, shrines, and reliquaries were made to order in Constantinople, or given as presents to foreign churches.

During the seventh, eighth, and ninth centuries it was customary for kings and queens to present votive crowns to their churches: these crowns were treasured with other precious articles, and hung up in the sanctuaries.

There is still preserved in the Cathedral at Monza the Iron Crown of the Lombard kings. It was given to the cathedral by Theodolinda the Lombard Queen in 616. The Iron Crown is so called from its having a thin band of iron encrusted in the inside, said to have been made from a nail from the Cross. It is really a band or collar of gold, studded with tallow-cut precious stones.

St. Eloi, who rose from the rank of goldsmith to a bishop (588-659) made crowns and other articles for church uses for the Church of St. Denis at Paris. The bronze-gilt chair of St. Dagobert (Fig. 134) is ascribed to him. He founded the Abbey of Solignac, near Limoges, where he established a school of working goldsmiths, which supplied many important works for various churches in France.

In the year 1858 at Guarrazar, near Toledo, in Spain, another valuable "find" was discovered, consisting of no less than eleven votive crowns or diadems, with other valuables, all buried close to the surface of the ground. The crowns are of pure gold, and are set with precious stones, such as sapphires and pearls. The rest of the treasure consists of three crosses, a large emerald stone, and several fragments of gold plates with chains attached.
