ries. He wrote a series of smaller medical
treatises on "The Activity of Medicines," on "Phthisis" and on
"Medical Dosage." He also wrote "On the Pulse and on Urine" in a
volume of which editions were issued at Venice and at Lyons.

Another of the physicians of Pope John XXII was Dino del Garbo, a
Florentine, the son of Bruno del Garbo, a skilful surgeon and the
disciple of Taddeo of Florence. He is sometimes known as {435} Dino
the Expounder because of his successful devotion to the exposition of
Galen and Avicenna. Like many of the physicians of his time he had
degrees in both medicine and philosophy and was celebrated for his
scholarliness. According to Van der Linden, he wrote _De Caena et
Prandio Epistola_, which was published by Jerome of Cartularius in
1545; Commentaries on Hippocrates' Nature of the Foetus, Venice, 1502;
a treatise on surgery which was published at Ferrara in 1485 and a
subsequent edition at Venice in 1536. His Commentaries on Avicenna and
the General Practice of Medicine were published at Venice in 1495 and
his book on The Virtues of Simple Medicines, a commentary on the
Second Canon of Avicenna, was published at Venice the same year. Dino
is usually looked upon as one of the most distinguished contributors
to medicine in the fourteenth century. His son Thomas is said also to
have been in the service of the Popes and has written books on The
Reduction of Medicines, a Commentary on Avicenna and a commentary on
Galen's work "On Fevers."

Urban V (1362-70).--Of Guy de Chauliac, physician to the Popes at
Avignon, enough has been said in the text of this book to make clear
how important was his place in the surgery of his time and, indeed, of
all the modern time. I have written on him more at length in my Old
Time Makers of Medicine (Fordham University Press), and during the ten
years that have elapsed since the writing of the original edition of
this volume on The Popes and Science, Guy de Chauliac's fame and
merits have come to be recognized everywhere.

Gregory XI (1370-78).--One of the well-known physicians of the Popes
at Avignon was Jean de Tornemire, known by his Latin name of
Tornamira, the physician of Pope Gregory XI, who on the death of that
Pope went to Montpellier, where he became Dean and Chancellor of the
Medical Faculty. Gurlt, in his History of Surgery, says that he must
be "counted among the most learned
