Julius Mancinus of Siena, who secured the much coveted position of
physician to the Santo Spirito Hospital in Rome by competition. He
obtained a great reputation for his ability to make the prognosis of
disease and acquired an extensive practice as a consequence. He
accumulated a great fortune from his practice but lived very modestly
and used his income partly for the education of ambitious youths of
talent who were without the means of securing an education and partly
in the collection of works of art. He wrote a book on "The Pictures of
Rome." A number of books were dedicated to him, and Antonio Recchi in
his scientific work expresses his gratitude to him for the help
afforded in the collection of plants, animals, and minerals from
Mexico.

Two of the Papal Physicians of Pope Urban VIII were the uncle and
nephew Sylvester and Thaddeus Collicola. Sylvester taught medicine at
the Sapienza and was a very popular teacher mentioned in a number of
books of the time. Thaddeus had studied law before taking up medicine,
but devoted himself entirely to the second profession and Mandosius

contact with him." Thaddeus was evidently a friend of the literary men
of his time, for he is often mentioned by poets and writers. Several
books were dedicated to him by scientific and literary admirers.

treatise on Hippocrates' Suggestions concerning Air, Water and
Habitation, a book On Pleurisy, a detailed account of the fatal
illness and the autopsy on the body of Cardinal Bevilacqua and
academic lectures on poisons as well as a book on the Opobalsamo
Orientate.

A distinguished Papal Physician under Pope Innocent X was Paul
Zacchias, "a most learned philosopher and physician who had a very
versatile genius and whose deep interest in every form of intellectual
work, not only such serious studies as philosophy, {462} medicine,
theology and jurisprudence, but also the lighter arts of poetry,
music, painting and so forth, made him distinguished among his
contemporaries." Zacchias is best known as the author of a book on
medico-legal questions which went through a series of editions, was
