20 Christmas Carols written before the 1900s. 
Luke’s Nativity text in the New Testament, has been the inspiration to four well-known canticles, although their exact origins remain unknown:
- The Magnificat, in Luke 1:46–55, is spoken by Mary and is one of the eight most ancient Christian hymns, perhaps the earliest Marian hymn.
- The Benedictus, in Luke 1:68–79, is spoken by Zechariah, while the Nunc dimittis, in Luke 2:29–32, is spoken by Simeon.
- The traditional Gloria in Excelsis is longer than the opening line presented in Luke 2:14, and is often called the “Song of the Angels” given that it was uttered by the angels in the Annunciation to the Shepherds.
By the 13th century, the Franciscans had encouraged a strong tradition of popular Christmas songs in the native languages. Christmas carols in English first appear in a 1426 work of John Awdlay, a Shropshire chaplain, who lists twenty-five “caroles of Cristemas”.[Christ’s Mass] [https://en.wikipedia.org/]
