His close connections with leading European scientists such as Galileo, with scholars and philosophers, kept him fully informed of the latest archaeological and scientific discoveries, for all of which he attempted to provide a visual record in his Museo.

In addition, he collected a whole range of natural history, geological samples and fossils, botanical illustrations and drawings of microscope observations, in effect, wunderkammer of objects.

As antiquarian, Cassiano applied a new systematic methodology: classical monuments were painstakingly measured, drawn and annotated, in a manner that would not become usual until the mid-eighteenth century.

After the death of Federico Cesi, it was left to Cassiano dal Pozzo and Francesco Stelluti to conserve the precious inheritance of scientific instruments, books and research.

[4] His contemporary biographer was Carlo Dati, whose laudatory oration Delle lodi del Commendator Cassiano dal Pozzo was printed in Florence, 1664.

A comprehensive catalogue raisonné of the collection in thirty-four volumes is in progress of publication under the title The Paper Museum of Cassiano dal Pozzo.

It is being produced under the auspices of the Royal Collection Trust and the Warburg Institute, and with the support of the British Academy, the Accademia dei Lincei and the Académie des Inscriptions et Belles-Lettres.
