That thing of silk,

Sporus, that mere white curd of asses’ milk;

Satire or sense, alas! can Sporus feel,

Who breaks a butterfly upon a wheel?

A. Pope, Prologue to the Satires (1734).

⁂ This Lord John Hervey married the beautiful Molly Lapel; hence Pope says:

So perfect a beau and a belle

As when Hervey, the handsome, was wedded

To the beautiful Molly Lapel.
