physicians of Pope Clement VIII was Julius De
Angelis, who came of a well-known academic family with many members
distinguished in law and medicine. He was professor at Padua for years
and afterwards at the Sapienza in Rome and was chosen by the Pope to
give special lessons for the benefit of physicians and medical
attendants at the Santo Spirito Hospital in Saxia as it was called. He
is mentioned in a number of medical works of the time, and in the book
of the Statutes of the College of Physicians of the City of Rome.

Paul V (1605-21).--One of the physicians of Pope Paul V, though at
first he had refused the honor because it is said that as an
astrologer he had found the stars unfavorable to his acceptance of it,
was Pompeius Caimus, from whom we have a number of medical writings.
Van der Linden, in _De Scriptis Medicis_, and others furnish the list
of them. He wrote "On Congenital Heat," on "The Indications of Putrid
Fevers," on "The Recognition and Cure of Melancholia," on "The Nature
of Science and Its Acquisition," "On Grief," a "Treatise on Human
Longevity and the Climacteric Years," as well as "Dissertations on the
Aphorisms of Hippocrates, Galen and Avicenna," which had been
delivered as lectures at Padua, on "The Nature and Differences of
Winds," and on "The Early Recognition and the Lengthening of Old Age,"
besides translating and annotating a number of the works of the old
Greek philosophers and physicians in Latin. It may seem strange that a
man of such wide erudition and scholarship should still cling to the
delusion of astrology, but about this same time Galileo and Kepler
were drawing up horoscopes, and in the middle of the eighteenth
century Mesmer's astrological essay was accepted for the degree of
Doctor of Medicine at the University of Vienna. Caimus, after refusing
the chair of {460} medicine at the University of Pisa, to which a
magnificent salary was attached, became the physician to Pope Gregory
XV.

Gregory XV (1621-23).--Vincentius Crucius was another of the
physicians of Pope Gregory XV. He had been a professor at Bologna and
we have from him his lectures at Bologna on "Epilepsy or The Comitial
Disease," published at Venice in 1603. Books of his "On Catarrh,"
published at Ravenna, on "The More Frequent Diseases of The Head;
Catarrh, Phrenitis, Lethargy and Epilepsy," published at Rome, 1617,
and "The More Frequent Diseases of the Chest; Phthisis, Haemoptysis,
Asthma, Peri-pneumonia, an
