Despite its fragmentary condition, the shape and size of this engraved glass vessel identify it as a liturgical chalice. Comparisons to well-preserved silver chalices from the sixth and seventh centuries are numerous, though only one other glass example has survived, excavated at ancient Gerasa, in modern-day Jordan (Amman, National Archaeological Museum).
On one side, angels flank a jeweled cross inside a shrine. They hold books in covered hands signifying that the books are either Bibles or Gospels. The shrine is thought to reflect the monument in Jerusalem set up by Emperor Theodosios II (408–50) to commemorate Christ’s crucifixion on Golgotha. It was a major pilgrimage site, as the cross symbolized powerfully Christ’s triumph over death; worship there enhanced such a hope for all believers. On the chalice’s other, more fragmentary side, a man stands praying before a large jeweled cross. Between him and the cross is an omega, the last letter of the Greek alphabet; an alpha, the first letter, was no doubt placed between the cross and another praying figure of whom only the fingers are preserved. The letters refer to Revelation (1:8), “I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.” The quotation attests to the Lord’s omnipresence and his return at the end of time for the last judgment.
The liturgical role of the vessel, supported by the images, emphasizes salvation through worship of the cross. Belief in Christ’s triumph over death and partaking of the Eucharist were expressions of faith in an afterlife and salvation within the community of Christianity.
