The second, Deck the Hall, is a 16th-century Welsh melody, whose lyrics were written by the Scottish musician Thomas Oliphant in 1862. The German poet Johannes Daniel Falk wrote lyrics for a Catholic hymn called O Sanctissima, which has become the famous carol O du fröhliche o du selige. Finally, Alphonsus Liguori, an Italian priest, wrote this now well-known Italian carol, Tu Scendi dalle Stelle, in 1744.
