Giulio Mancini

Who was Giulio Mancini?

Giulio Mancini was a seicento physician, art collector, art dealer and writer on a range of subjects. His writings on contemporary artists like Caravaggio and Annibale Carracci remain one of our earliest sources of biographical information; his Considerazioni being an important source on art in early 17th-century Rome.

Mancini was born in Siena and attended the University of Padua, where he studied medicine, astrology and philosophy. He went to Rome in 1592, where he practised medicine; from 1595 at the Hospital of Santo Spirito. He became personal physician to pope Urban VIII in 1623. The pope was a notable patron of the arts, and their relationship was such that, in 1628, Mancini was made an apostolic protonotary and a canon of St. Peter's.

Mancini's writings went unpublished until the 20th-century; his Considerazioni sulla pittura, written between 1617 and 1621, remaining so until 1956. His advise to the collector gives us insight into the contemporary art market in Rome; his notes on spotting fakes were the first indication of how sophisticated these postiches had already become by the early 17th-century.

In the Considerazioni, he distinguishes four tracts of painting in his contemporary Rome: that of Caravaggio; that of Carracci; the third of Giuseppe Cesari; and the fourth of everybody else, the mannerist painter Cristoforo Roncalli for instance. There is evidence that he knew, at least Caravaggio, well, having attended to the artist when he was ill and staying at the Palazzo Madama, probably in 1595. Mancini was also well acquainted with Caravaggio's benefactor, Francesco Maria del Monte.
