None e'er by proof two other faulchions chose

  For sound and solid, able to endure

  Three strokes alone of such conflicting foes,

  Passing all means and measure; but so pure,

  So perfect was their temper, from all blows

  By such repeated trial so secure,

  They in a thousand strokes might clash on high,

  — Nay more, nor yet the solid metal fly.
