Shakespeare's Sonnets: Cupid laid by his brand and fell asleep,

Cupid laid by his brand and fell asleep,A maid of Diane's this advantage found,And his love-kindling fire did quickly steepIn a cold valley-fountain of that ground,Which borrow'd from this holy fire of loveA dateless lively heat still to endure,And grew a seething bath which yet men proveAgainst strange maladies a sov'reign cure.But at my mistress' eye love's brand new fired,The boy for trial needs would touch my breast.I, sick withal, the help of bath desired,And thither hied, a sad distemper'd guest, But found no cure: the bath for my help lies Where Cupid got new fire, my mistress' eye.
