To what serves Mortal Beauty?

To what serves mortal beauty | dangerous; does set danc-     ing blood the O-seal-that-so | feature, flung prouder form     Than Purcell tune lets tread to? | See: it does this: keeps warm     Men's wits to the things that are; | what good means - where a glance     Master more may than gaze, | gaze out of countenance.     Those lovely lads once, wet-fresh | windfalls of war's storm,     How then should Gregory, a father, | have gleand else from swarm-     ed Rome? But God to a nation | dealt that day's dear chance.     To man, that needs would worship | block or barren stone,     Our law says: Love what are | love's worthiest, were all known;     World's loveliest - men's selves. Self | flashes off frame and face.     What do then? how meet beauty? | Merely meet it; own,     Home at heart, heaven's sweet gift; | then leave, let that alone.     Yea, wish that though, wish all, | God's better beauty, grace.
