A Christmas carol (also called a noël, from the French word meaning “Christmas”) is a carol (song or hymn) whose lyrics are on the theme of Christmas, and which is traditionally sung on Christmas itself or during the surrounding holiday season
While “Corde natus ex Parentis” isn’t a popular Christmas song today, it is probably the oldest known Christmas song that is still performed by a few churches today. The song, which is actually a Christian hymn, was written by Roman Christian poet Aurelius Prudentius.
Christmas carols are very popular in Poland, where they have a long history, the oldest dating to the 15th century or earlier. There is a tradition of singing Christmas carols until 2 February which is celebrated by western Christians as the Feast of the Presentation of Jesus at the Temple.
