What did Benjamin Franklin epitaph say?

In 1728, when Franklin was 22, he composed a mock epitaph, which is well-known today:

The body of

B. Franklin, Printer

Like the Cover of an Old Book

Its Contents torn Out

And Stript of its Lettering and Gilding)

Lies Here, Food for Worms.

But the Work shall not be Lost;

For it will (as he Believ'd) Appear once More

In a New and More Elegant Edition

Revised and Corrected

By the Author.

However, his gravemarker reads simply:

BENJAMIN

And
