And wear it, Medon, for it may ensue,
That thou, by virtue of this massy chain,
A stronger town than Boulogne mayst subdue,
If wise men's saws be not reputed vain;
For what said Philip, king of Macedon?
"There is no castle so well fortified,10
But if an ass laden with gold comes on,
The guard will stoop, and gates fly open wide."
