A song from one of the "Pastorelas". "Las Pastorelas" or "Los Pastores" as they're sometimes called, are the "Shepherd's Plays" that Mexicans perform during Christmastime. The dialogue and details of the plot vary from place to place, but they all portray the journey of the shepherds to see the Christ Child in Bethlehem. Along the way they receive help and obstacles from angels and devils and face many temptations. The plays are often accompanied with music and song. The song below is from an album by singer Óscar Chávez.
“A frozen December appears to come,
the rose of April will bear fewer flowers.
How beautiful is the countryside, how beautiful are the flowers;
how beautiful is the song of the nightingales.
Upon the horizon the shadow walks,
we greet the peace from Palestine.
Crystal water, transparent ice;
Blessed is He who comes, the King of Heaven!”
