John Bunyan (28 November 1628 – 31 August 1688 / Elstow, Bedfordshire, England.)

What is the vine, more than another tree?
Nay most, than it, more tall, more comely be.
What workman thence will take a beam or pin,
To make ought which may be delighted in?
Its excellency in its fruit doth lie:
A fruitless vine, it is not worth a fly.

Comparison.
