When Love with unconfined wings
  Hovers within my Gates;
And my divine Althea brings
  To whisper at the Grates:
When I lye tangled in her haire,
  Or fetterd to her eye;
The Gods, that wanton in the Aire,
  Know no such Liberty.

When flowing Cups run swiftly round
  With no allaying Thames,
Our carelesse heads with Roses crowned,
  Our hearts with Loyall Flames;
When thirsty griefe in Wine we steepe,
  When Healths and draughts go free,
Fishes that tipple in the Deepe,
  Know no such Libertie.

 ... 

Stone Walls doe not a Prison make,
  Nor I'ron bars a Cage;
Mindes innocent and quiet take
  That for an Hermitage;
If I have freedome in my Love,
  And in my soule am free;
Angels alone that sore above,
  Injoy such Liberty.
