Which thought that steel both trusty was and true
And needed not a foil of contraries,
But shewed all things even as they were in deed.
In stead whereof, our curious years can find
The crystal glass, which glimpseth brave and bright,
And shews the thing much better far than it,
Beguiled with foils, of sundry subtle sights
So that they seem and covet not to be.
