Which, ever since that charme, hath beene

As hard, as that which grav'd it, was;

Thine eyes will give it price enough, to mock

The diamonds of either rock.[4]

While he is absent, the characters he has cut in the glass will, the poet hopes, magically defend his mistress against the seductive entreaties of his rivals.

In 1711 in a satiric letter to The Spectator, John Hughes poked fun at a number of aspiring poets who had recently attempted to create works of art by utilizing what Hughes called "Contractions or Expedients for Wit." One Virtuoso (a mathematician) had, for example, "thrown the Art of Poetry into a short Problem, and contrived Tables by which any one without knowing a Word of Grammar or Sense, may to his great Comfort, be able to compose or rather erect Latin Verses." Equally ridiculous to Hughes, and more relevant to the concerns of this introduction, was the practice of another poet of his acquaintance: "I have known a Gentleman of another Turn of Humour, who, despising the Name of an Author, never printed his Works, but contracted his Talent, and by the help of a very fine Diamond which he wore on his little Finger, was a considerable Poet upon Glass. He had a very good Epigrammatick Wit; and there was not a Parlour or Tavern Window where he visited or dined ... which did not receive some Sketches or Memorials of it. It was his Misfortune at last to lose his Genius and his Ring to a Sharper at Play; and he has not attempted to make a Verse since."[5]

But "Epigrammatick Wits" of this sort were not universally despised in the eighteenth century. In 1727 in a "critical dissertation prefix'd" to A Collection of Epigrams, the anonymous editor of the work argued that the epigram itself "is a species of Poetry, perhaps, as old as any other whatsoever: it has receiv'd the approbation of almost all ages and nations...." In the book proper, he found room for a number of epigrams which he evidently copied from London window panes. Here is an example:
