May not this conceivably be the Bacon of the popular saying?

The curious Dunmow Custom, by which a Flitch of Bacon has been given to married folk who have sworn that, for a year and a day, they have neither had differences nor wished themselves unwed, is certainly very old.

It may, indeed, have come over with the Conqueror. More than one book of antiquities avers that "at the abbey of Saint Melaine near Rennes"—the old capital of Brittany—there had been hanging, for more than six centuries, a side of Bacon "still quite fresh," which had been set apart for the first pair who "for a year and a day had lived without dispute and grumbling" and without repenting of their marriage.

To the Dunmow Custom we have a reference not only in old Chaucer, but in that great song of England, The Vision of William concerning Piers the Plowman, written under the shadow of the Black Death. Says the good Langland—

Many a couple since the Pestilence
Have plighted them together;
The fruit that they bring forth
Is foul words
In jealousy without happiness,
And quarrelling in bed;
They have no children but strife,
And slapping between them,
And though they go to Dunmow
(Unless the Devil help!)
To follow after the Flitch
They never after obtain it;
And unless they both are perjured,
They lose the bacon.[*]

[*] The last four lines appear as follows in the "C-text" of Professor Skeat's monumental two volume edition of the poem—

Thauh thei don hem to Donemowe . bote the deuel hem helpe
To folwen for the flicche . feccheth thei hit neuere;
Bote thei bothe be for-swore . that bacon thei tyne.

Then in Reliquiae Antiquae, which dates back to the fifteenth century, another poet, discoursing in relation to the Seventh Commandment, laments that he can

fynd no man that will enquere
The parfyte wais unto Dunmow;
For they repent them within a year,
And many within a week and souner men trow.

Yet another century later one Howell says choicely—
