This new Catalogue Raisonne, Part III in the series on Natural History,
is based on the collection originally formed by Prince Federico Cesi in
the early 17th century and later acquired by Cassiano. These drawings
constitute the first truly scientific study of fossilized woods and are
executed with such finesse, skill and detail that they will be of
immense interest both to art-historians and to historians of science.
The drawings, the majority of which have remained unstudied and
unpublished until now, include specimens of wood and animal fossils,
ammonites and concretions, pyrits and baked clays, as well as a series
of field drawings giving the sites where these specimens were found. The
introductory essays discuss the background to Cesi's project as well as
the importance of the drawings to the history of seventeenth- century
culture and science.
