Walking Back Margaret Paston's Famous Letter, Already?

Representative Medieval Woman
at Her Writing Table.
My recent piece “Margaret Paston’s Famous Letter” was only the beginning of my research in the matter of sugar in the medieval world.  It didn’t take long to realize that there was more available on the subject than my persistent search over some months (and general search over some years) had found — much more.

I had been leery to accept the common claim that a Venetian had received 100,000 crowns, in 1420, for inventing a higher quality process to make sugar product.  Still, for all I could not find a precise citation for the claim, it was to be found in nearly every history of sugar written in the past two centuries.  In my own rendition, I asserted that:

A very important obstacle was removed in 1420.  It was in this year that Venice learned to process sugar into blocks referred to by all as “sugar-loaves”.  The purity level was so high that the whole idea of sugar was changed.  The block form allowed much easier handling and prevented the common problem of infestation from insects.
But scholarship should not depend upon faith and I have since found myself embarrassed to have to admit, foremost, that sugar loaves had already existed for centuries.

Between the Octave of Epiphany[1] and the beginning of Pentecost, in 1290, servants of Richard de Swinfield, Bishop of Hereford, purchased “sugar loaves”[2] on three occasions.  According to MacPherson’s Annals of Commerce, so early as the year 1329, loaves of sugar were sold in Scotland at the price of 1s. 9 1/2 d.  No information is available on the purity or the granularity of the product.[3] 


Moreover, a few days of searching on this matter revealed that the 1420 claim flowed from a single source: Peter Heylyn’s Cosmographie.[4]   I have quoted Heylyn’s delightful work before but always careful to inform the reader that he cited no sources for any of his claims.  If he made a claim that could not be cross-checked, the only choice was to take his word for it.  Or not, for, while he generally proved to be right when he could be checked, he was by no means always so. 

But I had checked the 1420 claim after a fashion.  Circumstantial historical evidence does indeed show, time and again, that sugar was first consumed in quantity in England sometime in the mid-to-late 15th century.  And, until Antwerp could wheedle the formula out of one or another Venetian merchant, in the mid-16th century, Venice dominated refined sugar sales to all of Europe.  No other manufactory competed with Venice according to commercial records, for quality of product, and subsequent sales, unless it was Cyprus which the Venetians occupied at the time.

Far more to the point, in his Opera domini Joannis de Vigo in chyrurgia,[5] Lyon, 1521, the surgeon Giovanni da Vigo, was the first in history to describe drilling and filling teeth by way of treatment of cavities.  In 1548, Walter Hermann Ryff, of Strasburg, published his Useful Instruction on the Way to Keep Healthy, to Strengthen and Reinvigorate the Eyes and the Sight. With Further Instruction on the Way of Keeping the Mouth Fresh, the Teeth Clean, and the Gums Firm.[6]  While some limited portion of earlier anatomy books had made observations about the mouth and teeth, Ryff’s books were collections of practical knowledge from past and present.  A considerable portion of the text dealt with mouth, teeth, care and extractions.  The book was in German rather than Latin.

Vigo’s was the first of an explosion of books about practical dentistry.[7]  The tools of dental surgery were depicted and their operation explained.  By the end of the century, Peter van Foreest of Alkmaar’s, Complete Works in Four Volumes,[8] Antwerp, 1597, shows us that, during the late 16th century, he was  strongly recommending patients avoid sweets and sugar in order to save themselves the pain of repeated dental surgery.


While sugar had been around for centuries, and available, at least from the 13th century, to those in England willing to make arrangements for special shipment of small quantities and to pay an enormous price, rather than sweeten their food with honey, something clearly changed at around the end of the 15th century.  That something seems to have begun around 1420 in Venice.

First, of course, the price came down precipitously.  Secondly, the facts suggest, the refining of sugar may first have reached the point in Venice, during the 15th century, at which the purity improved the experience and the method of granulation allowed for sugar loaves that would be able to be broken into grains, for cooking and sprinkling, rather than into chunks or heated into a syrup or cut into slabs.

Be all of this as it may, Margaret Paston has still left us the first record of sugar loaves that were able to be regularly purchased from merchant’s shelves.  It was an expensive luxury but a wealthy commoner could afford it.

(above an ounce of standard silver) by the pound. So Dr. Heylin is surely mistaken, at least in the date of the invention of sugar-baking.”
[4] The edition quoted is always shown as the “first edition” of 1624 the existence of which has proven impossible to verify.  "The boiling and baking of sugars as it is now used, is not above 200 years old; and the refining of it more new than that first found out by a Venetian in the days of our forefathers, who got 100,000 crowns by the invention; before which art of boiling and refining it, our ancestors made use of it rough as it came from the canes. But they most commonly used honey instead of it.”  The rest of the bibliographical world seems to think that the first edition was published in 1652.  No available edition, however, includes the quote that appears invariably in sugar history after sugar history.
