Constance retorting:

Now shame upon you whether she does or no!

His grandam’s wrongs, and not his mother’s shames,

Draws those heaven-moving pearls from his poor eyes,

Which Heaven shall take in nature of a fee:

Ay, with these crystal beads Heaven shall be bribed

To do him justice and revenge on you.

Bolingbroke in “Richard II” (Act 1, Scene 1) says:

Since the more fair and crystal is the sky,

The uglier seem the clouds that in it fly.
