Richard Lovelace (1618-1657). And by the way, don't you just love that last name?! Mr. Lovelace was a courtier, soldier and gentleman poet who in 1642 presented the Kentish petition to Parliament. This was a Royalist document calling for the restoration of the rights of King Charles I. He was promptly imprisoned for this action.
Although he was eventually released he suffered another period of imprisonment and died in very reduced circumstances as a hopeless drunkard. His poem reads:
Stone walls do not a prison make
Nor iron bars a cage;
Minds innocent and quiet take
that for a hermitage
If I have freedom in my love
And in my soul am free
There are two more lines which I haven't used on the piece. They read:
Angels alone that soar above
enjoy such liberty.
While still thinking about this and how amazing it is that someone living almost 4 centuries ago thought along the same lines as I did, I bought some artistic packing tape at the Crossing Borders exhibition in Peebles (from GraceInk Design) that featured bird cages and I then remembered I also have a cird cage stencil.
