"The inscriptions in the arches above Mary and St. John extol the Virgin's virtue and purity and St. John's greatness as the forerunner of Christ. The particularly significant inscription above the Lord's head translates: 'This is God, all-powerful in his divine majesty; of all the best, by the gentleness of his goodness; the most liberal giver, because of his infinite generosity.' The step behind the crown at the Lord's feet bears the inscription: 'On his head, life without death. On his brow, youth without age. On his right, joy without sadness. On his left, security without fear.'" (Kleiner, p.567)
