The oldest hymn to the Theotokos

So far, the earliest known prayer to the Virgin Mary is known as “Beneath thy compassion” (Greek: Ὑπὸ τὴν σὴν εὐσπλαγχνίαν). The earliest text of this hymn was found in a Christmas liturgy of the third century. It is written in Greek and dates to approximately 250 A.D.

In 1917, the John Rylands Library in Manchester acquired a large panel of Egyptian papyrus including the 18 cm by 9.4 cm fragment shown at left, containing the text of this prayer in Greek.

C.H. Roberts published this document in 1938. His colleague E. Lobel, with whom he collaborated in editing the Oxyrhynchus papyri, basing his arguments on paleographic analysis, argued that the text could not possibly be older than the third century, and most probably was written between 250 and 300. This hymn thus precedes the “Hail Mary“ in Christian prayer by several centuries.
