The Placing of the Honorable Sash of the Most Holy Theotokos
Although the historical accounts differ somewhat, the Deposition that is celebrated today took place most likely during the reign of Emperor Arcadius (395-408), when the precious Cincture of the Mother of God was brought from Zela of Cappadocia to Constantinople, and placed in the Church of the Theotokos in the section of Chalcopratia.
Apolytikion in the Plagal of the Fourth Tone
O Ever-Virgin Theotokos, shelter of mankind, thou hast bestowed upon thy people a mighty investure, even thine immaculate body's raiment and sash, which by thy seedless childbirth have remained incorrupt; for in thee nature and time are made new. Wherefore, we implore thee to grant peace to the world, and great mercy to our souls.
Kontakion in the Second Tone
Thy precious sash, O Theotokos, which encompassed thy God-receiving womb, is an invincible force for thy flock, and an unfailing treasury of every good, O only Ever-virgin Mother.
