Double Chi Rho / Alpha Omega Medallion from SNV 36 Key Ring

This small detail of a medallion, taken from an antique image of St. Cecilia (SNV 36) q.v., is full of Christian symbolism. The Chi Rho and the Alpha and Omega are, besides the cross and fish, two of the oldest Christian symbols. The Chi Rho, also known as the chrismon or sigla, is formed by the superimposition of the first two capital letters of the Greek word ΧΡΙΣΤΟΣ (Christos), the centre of the chi (Χ) being intersected by the vertical stroke of the rho (Ρ). The additional letters, the Alpha (Α) and Omega (Ω, lowercase: ω), the first and last letters of the Greek alphabet, which flank the chrismon, symbolise the eternal existence of Jesus and of God. In Revelations, Christ is quoted as saying: “I am the alpha and the omega; the beginning and the end" (Revelation 21:6, 22:13 - Douay-Rheims 1899 American Edition [DRA]). + Image Credit (SNV 36): Detail from an antique image of St. Cecilia of Rome from a late 19th-century devotional print, artwork by J.
