Hail the night, all hail the morn. [Christmas.] This appeared in an anonymous volume of Christmas Carols, published in London, in 1837. It passed into the American Sabbath Hymn Book, 1858, No. 278, and again into later collections. It is usually given as "From the German," but the German original (if any) has not been found.
