Dikirion and Trikirion
Dikiri and trikiri are liturgical candlesticks, often quite ornate, used by a bishop.
Both dikiri and trikiri have a flat base, so that they may be stood upright. Above this base is a vertical shaft terminating in candleholders. The dikiri holds two candles, representing the dual nature of Jesus Christ (i.e. fully God and fully man), and the trikiri holds three, representing the Three Persons of the Holy Trinity.
During a hierarchical Divine Liturgy, the dikiri and trikiri are kept respectively on the northeast and southeast corners of the Altar or on stands placed next to these corners. When they are needed by the bishop, they are carried to him by subdeacons, who may also carry them during the censing by the deacon or during the Great Entrance.
