The _saccos_, formerly the principal vestment of the patriarchs and an emblem of sovereign power, is now common to all Russian bishops. It is in the shape of a dalmatic, formed of two square pieces of stuff joined together at the neck and open at the sides, having wide short sleeves. Many of the finest of these vestments are elaborately embroidered in gold and silver and ornamented with figures of saints; and in the stuffs themselves sacred subjects are often woven. They are also thickly sown with rows of seed-pearls which follow the lines and edgings of the vestment and border the sacred images. They are besides set with enamelled, nielloed, or jewelled plaques of gold or silver. Texts in Greek or Sclavonic often border the whole of the edges of the garment. These are elaborately worked in gold or silver, or the letters formed completely of seed-pearls. The _saccos_ of the Metropolitan Peter (made in 1322), of Alexis (1364), of Photius (1414), and of Dionysius (made in 1583), are remarkable vestments of this character, to be found in the patriarchal sacristy at Moscow. The stoles, which usually correspond, are long, narrow, and nearly straight-sided to the bottom. A peculiar episcopal ornament is the _epigonation_. It is a large lozenge-shaped ornament embroidered and worked in a similar manner to the other vestments, and by bishops is worn hanging from the right side. The usual form of mitre of a pope of the Russian church is well-known. The earlier kind was a sort of low cap with a border of fur, something like the cap of a royal crown, and probably not different in type from the head-dresses of bishops of the west. Some are sewn thick with pearls bordering and heightening the lines of the figures of saints, and forming the outlines of the Sclavonic inscriptions. Such is that of Joassof, first patriarch of the Russian church (1558). Those of later times are often of metal richly set with precious stones. Sometimes they assume a more conical form, surmounted by a cross, like an imperial crown, as that which is termed the Constantinople mitre, said to have been made in the time of Ivan the Terrible. The mitre of the celebrated Nikon (1655), who aspired to papal prerogatives, is diadem-shaped and remarkable for the richness of the precious stones with which it is set. The most usual shape recalls to some extent the favourite cupola, spreading out from the base to the top. The form of the chalice used in the Russian church varies considerably, as it does also in that of the Latin church. In general characteristics the two have much in common. In early times the chalice was made of wood or crystal as well as of gold and silver. An ancient chalice of crystal is preserved in the Cathedral of the Assumption at Moscow, and the wooden ones of SS. Sergius and Nikon are in the sacristy at Troitsa. On some old icons our Lord is represented as giving the holy communion to the apostles out of narrow-necked vessels which appear to be made of alabaster.
