==Embalming technique==
Ruysch researched many areas of human [[anatomy]], and physiology, using spirits to preserve organs, and assembled one of Europe's most famous anatomical collections.<ref>Israel, J.I (1995) The Dutch Republic: Its Rise, Greatness and Fall, 1477-1806, p. 907.</ref> His chief skill was the preparation and preservation of specimens in a secret ''liquor balsamicum'', and he is believed to be one of the first to use arterial [[embalming]] to this effect. He developed an injection from mercuric sulfide, which originated from cinnabar, a naturally occurring red-colored mineral. The injection gave many specimens a reddish, almost lively expression. Thanks to this technique, observers could visualize and dissect even the smallest blood vessels, which was a groundbreaking technique in the 17th century. Ruysch's revolutionary embalming techniques also allowed for the corpses to be preserved for a greater period of time. This not only extended the time allowed for each dissection presentation but also made it possible for these presentations to take place during the warmer months.<ref name=":0">{{Cite journal|last=Hansen|first=Julie V.|date=December 1996|title=Resurrecting Death: Anatomical Art in the Cabinet of Dr. Frederik Ruysch|journal=The Art Bulletin|volume=78|issue=4|pages=663–679|doi=10.2307/3046214|jstor=3046214}}</ref>
