The Large Sakkos of Photius (Russian: Большой саккос митрополита Фотия; also known as the Major Sakkos) is a satin tunic embroidered with gold and silver thread and decorated with silk and pearl ornament, approximately 4 ft 5 in long.
[1] It is a luxury item created in the late Byzantine era for Photius, the Metropolitan of Kiev and all Rus' based in Moscow, around 1417.
The satin sakkos is embroidered with gold and silver thread and colored silks outlined with pearls.
[1] Dozens of religious and secular figures appear on the sakkos in an array of rectilinear, L-shaped, cruciform, and circular frames.
All around are various Orthodox Church feasts and figures of saints, as well as Old Testament scenes, including the binding of Isaac, linked with the Crucifixion of Christ.
