Christmas carols: Drei Könige wandern aus Morgenland
Peter Cornelius was a 19th century German composer who composed three operas (although the third was left unfinished) as well as a number of Weihnachtslieder (Christmas carols). This one, "Drei Könige wandern aus Morgenland," was published in 1871. The first two versions I've linked are in German, the third is in English.
