Classic Poem

Can you paint a thought? or number
Every fancy in a slumber?
Can you count soft minutes roving
From a dial's point by moving?
Can you grasp a sigh? or, lastly,
Rob a virgin's honour chastely?
No, oh no! yet you may
Sooner do both that and this,
This and that, and never miss,
Than by any praise display
Beauty's beauty; such a glory,
As beyond all fate, all story,
All arms, all arts,
All loves, all hearts,
Greater than those, or they,
Do, shall, and must obey.
