Starting in 1620 he reproduced in etchings part of his collection of animal skeletons owned by Johann Faber, a Bavarian physician-naturalist residing in Rome and a member of the scientific Accademia dei Lincei.
He is the recipient of twenty honorary degrees from Australian, British, Canadian, Chinese, Dutch, Egyptian, French, Italian, Japanese, Spanish, and U.S. universities, and has been elected to honorary membership in over fifteen foreign academies, including the Royal Swedish Academy of Sciences, the American Philosophical Society, the American Academy of Arts and Sciences, the Accademia dei Lincei (Rome), and the Russian Academy of Sciences.
After the Accademia dei Lincei in Rome and the Académies Royales in Paris, the Prussian Academy of Art was the oldest institution of its kind in Europe, with a similar foundational mission to other royal academies of that time, such as the Real Academia Española in Madrid, the Royal Society in London, the Royal Swedish Academy of Sciences in Stockholm or the Russian Academy of Sciences in St Petersburg.
