Though the cross is one of the simplest of forms, it is probably the most poignant. For Christians, the cross is the most potent symbol in existence, representing the earthly suffering, spiritual liberation, resurrection, and eternal life of Jesus Christ. The fact that an instrument of death was turned into a symbol of spiritual rebirth is amazing in itself. This is especially true for the faithful, and the Byzantine age was certainly one of fervent piety and extreme fanaticism. In terms of religious expression, this lovely cross falls into the category of gentle piousness and deep devotion.
