The Cross Poem by Pedro Calderon de la Barca

TREE which heaven has willed to dower
With that true fruit whence we live,
As that other death did give;
Of new Eden loveliest flower;
Bow of light, that in worst hour
Of the worst flood signal true
O'er the world, of mercy threw;
Fair plant, yielding sweetest wine;
Of our David harp divine;
Or our Moses tables new;
Sinner am I, therefore I
Claim upon thy mercies make;
Since alone for sinners' sake
God on thee endured to die.
