If not in one edition, yet in another, of every work of Francis Bacon, it will be found that the paper on which it is printed is watermarked with a design of grapes in various forms.

The following extract from his Novum Organum shows why he chose a grape design as a watermark in his various books.

"Whereas I pledge mankind in a liquor pressed from countless grapes--from grapes ripe and fully seasoned, collected in clusters, and gathered, and then squeezed in the press, and then, finally, purified and clarified in the vat."

Is it a coincidence that the watermark in the last page of The First Folio (the number of which is reversed) is a grape design with two letters C (one of which is reversed ), C being the Roman numeral for 100, and 100 being the simple count or seal of the name "Francis Bacon?"
