Gilbertus Anglicus

I've talked before about John of Gaddesden, a late-13th-century doctor who wrote a compendium of medical knowledge. A little before him was another who created an encyclopedic work about what was known at the time of medicine and surgery.

His name was Gilbertus Anglicus (c.1180 - c.1250), called so because he was born in England, although after some initial education in his home country he went to Europe to study, particularly at the Salerno medical school. He actually returned to England for a time to assist a bishop, but that bishop died in 1205 and Gilbertus went back to Europe.

After 1230, he produced a seven-volume work in Latin called Compendium Medicinae. This work was copied and distributed as one of the foundational works of medical education for centuries (along with Gaddesden's). It was translated into Middle English in the early 1400s. It first saw formal print in 1510 with further editions, one as late as 1608. Chaucer includes him in the Canterbury Tales as one of the great physicians.

Among its seven volumes was a section on gynecology that was sometimes circulated separately as The Sickness of Women. Later it was called The Sickness of Women 2 after having a different author's work added. These became even more widely distributed than the Trotula.

One of the aspects that made Gilbertus' Compendium so valued was its inclusion of the knowledge of so many others. Pythagoras, Hippocrates, Plato, Aristotle, Galen are there, of course, but also Avicenna and Averroes, Macrobius, Boethius, several Arabians, Isaac Judaeus, and the Salernian writers.

Isaac Judaeus was mentioned briefly here regarding Charlemagne and an elephant, and I'd like to tell you more about him, starting tomorrow. Isaac, that is, not the elephant.

John of Gaddesden

With us there was a doctor of physic;
In all this world was none like him to pick
For talk of medicine and surgery;
For he was grounded in astronomy. —Prologue to the Canterbury Tales

Doctor, from the Ellesmere MS.

John of Gaddesden (c.1280-1361) was a "Doctor of Physik" who was quite well-known in his day, so much so that modern scholars looking to find analogs for the characters in Chaucer's Canterbury Tales have suggested he is the likeliest candidate for Chaucer's "doctor of physic." As a fan of both Chaucer and historical detail, I'm going to weigh in and say . . . maybe.

Who was Gaddesden, and why was he considered the model for Chaucer's pilgrim? For one thing, he had written Rosa medicinæ (The rose of medicine; sometimes called the Rosa Anglicæ), a compendium of medical information called so because it was in five parts, like the five sepals of a rose. In it, he quotes numerous authorities from the past; Chaucer's list of authorities with whom his doctor is familiar lines up nicely with Gaddesden's sources. Also, Gaddesden had a reputation for charging high fees, and Chaucer makes it clear that his doctor loved gold.

To be honest, however, Gaddesden's book was quoting the same authorities that anyone would quote when compiling a book on medicine. It was completely unoriginal. Even his title seems derivative, probably based on Lilium medicinæ (the Lily of medicine) by Bernard Gordon, produced at Montpellier in 1303. Gordon, a Scotsman, was one of the teachers of Guy de Chauliac. Chauliac, in turn, taught Gaddesden. What did Chauliac think of his student's work? Not much; he said of it:

Last of all arose the scentless rose of England, in which, on its being sent to me, I hoped to find the odor of sweet originality, but instead of that I encountered only the fictions of Hispanus, of Gilbert, and of Theodoric.

Those who write about Gaddesden being Chaucer's doctor usually justify it also be calling them "contemporaries." Let's look at the timeline: the Canterbury Tales probably wasn't started until 1387. Even if the Prologue were the first thing he wrote—highly unlikely—this was a quarter century after Gaddesden's death; a death that would have taken place when Chaucer was about 20 years old and had been connected to the household of Prince Lionel, the second son of King Edward III, only for a few years. Gaddesden seems to have been attached to the household of Edward, the Black Prince, who would have spent much of Gaddesden's later years on the continent while Chaucer was in England.

They could have crossed paths, but probably not significantly, and Gaddesden would have been long out of the public eye and consciousness when Chaucer came into his own as a poet. For Chaucer to write up a physician who quoted historical authorities, knew astrology, and loved gold probably just meant that he had met typical physicians.
