“A curious artist wrought ’em—
With joints so close as not to be perceived;
Yet are they both each other’s counterparts!
(Her part had Juan inscribed; and his had Laydor;
You know those names were theirs;) and in the midst
A heart divided in two-halfs was placed.
Now if the rivets of those rings, inclosed,
Fit not each other, I have forged this lie,
But if they join, you must for ever part.”
Gimmal rings, though originally double, were, by a further refinement, made triple and even more complicated, yet the name remained unchanged.
