The Caged Bird
 
This bird was happy once in the high trees
You cage it in your cellar, bring it seed,
Honey to sip, all that its heart can need
Or human love can think of:  till it sees,
Leaping too high within its narrow room
The old familiar shadow of the leaves,
And spurns the seed with tiny desperate claws.
Naught but the woods despairing pleads,
The woods, the woods again, it grieves, it grieves.

                   Bothius, Roman 480 524 AD
