Salve Festa Dies

Recorded at the Basilica of St. Patrick's Old Cathedral
Basilica Schola
New York City, 12/12
Recorded by Malcolm Addey

The oldest hymn to the Theotokos (BVM), found in a Coptic Orthodox Christmas liturgy of the third century. 

Under thy protection
we seek refuge,
Holy Mother of God;
despise not our petitions
in our needs,
but from all dangers
deliver us always,
Virgin Glorious and Blessed.

Sub tuum praesidium
confugimus,
Sancta Dei Genetrix.
Nostras deprecationes ne despicias
in necessitatibus nostris,
sed a periculis cunctis
libera nos semper,
Virgo gloriosa et benedicta.

Ὑπὸ τὴν σὴν εὐσπλαγχνίαν,
καταφεύγομεν, Θεοτόκε.
Τὰς ἡμῶν ἱκεσίας,
μὴ παρίδῃς ἐν περιστάσει,
ἀλλ᾽ ἐκ κινδύνων λύτρωσαι ἡμᾶς,
μόνη Ἁγνή, μόνη εὐλογημένη.

Sub Tuum Praesidium
