What is it like to reveal the wonders and marvels of the very small?
“I have contemplated a great many animals with infinite admiration; among them, the flea is most horrible, the mosquito and the moth are beautiful; and with great satisfaction I have seen how flies and other tiny creatures can walk attached to mirrors, and even upside down.”
Galileo, letter to Cesi, 1624
Galileo and the Academy of the Lynx were responsible for the first published report of observations made with a microscope (Apiarium, 1625), as well as for the telescope. At the same time Galileo was making his telescopic discoveries, he was also experimenting with lenses to magnify the small. Another member of the Lynx, Johann Faber, named Galileo’s new instrument a microscope. In antiquity, the lynx was renowned for possessing sharp eyesight at night. The founder of the Academy of the Lynx, Federigo Cesi, believed that the eyes of the Lynx would peer more deeply into the secrets of nature than ever before. The keen eyes of the Academy of the Lynx stretched the boundaries of European thought in the life sciences just as with Galileo’s discoveries in the physical sciences.
Section 1: Apiarium: The Lincean Explorer
“so, to make it capable of being minutely investigated with the eyes, we applied the Lincean explorer, that is to say, the microscope, a small viewing glass enclosed in a tube.” G.B. Ferrari
In 1623, Galileo’s supporter and friend, Cardinal Maffeo Barberini, a patron of the Academy of the Lynx, became Pope Urban VIII. Barberini’s election seemed to assure Galileo of support from the highest level in the Catholic Church. To honor Urban and cement their relationship, the Academy of the Lynx published several works featuring the Barberini family crest of three busy bees. One of these works, a study of bees called the Apiarium, was the first published report of observations made with a microscope. Just as Galileo's telescope brought near the distant Moon and stars, the microscope enabled the Academy of the Lynx to fathom the secrets of the small, and portray a world never seen before.

Section 2: Marvels and Wonders
“So, naturalists observe, a flea Has smaller fleas that on him prey; And these have smaller still to bite 'em, And so proceed ad infinitum.” Jonathan Swift, “On Poetry: a Rhapsody” (1733)
As an instrument of discovery, the microscope revealed unseen worlds of surprising wonder and complexity. Anything placed under its lens became something new and different. The common flea and other specimens were transformed into fantastic otherworldly creatures which observers captured in detailed illustrations many thousands of times larger than life. As microscopy advanced, progress was made in optical design, lens grinding, and the mounts that held the parts together. In some cases, more complex designs were preferred for “refined intellectual entertainment.” The simple designs proved more effective for research, especially when examining specimens out in the field.

Section 3: Inquiries and Investigations
Innovations in microscopy supported sustained research in diverse subject areas. Microscopic investigations of human anatomy led to discoveries of red blood cells, papillae on the tongue, alveoli in the lungs, ova, and spermatozoa. The microscope facilitated study of the embryological development, yielding knowledge about life cycles of insects and aquatic animals and the development of the chick embryo. It made visible the processes of metamorphosis, the remarkable “death cycle” of tardigrades, and how hydra reproduce and feed. Microscope usage exceeded mere observation of the small. Naturalists developed advanced techniques for microscopic dissection, controlled experimentation, and measurement.

Section 4: Small Worlds Everywhere
minima cura si maxima vis
“Take care of small things if you want to obtain the greatest results”
Motto of the Academy of the Lynx
During the eighteenth century, microscopes became more affordable and widely available. George Adams’ Micrographia Illustrata (1771) and Philip Henry Gosse’s Evening at the Microscope (1859) show microscopes served both as research tools and as sources of refined intellectual “edutainment.” Today, health care workers in remote areas diagnose diseases using inexpensive smartphone-based microscopes, while advanced-generation Scanning Electron Microscopes serve as key research tools in state-of-the-art laboratories. At the University of Oklahoma, researchers at the Sam Noble Museum and the Noble Electron Microscopy Lab push forward the frontiers of knowledge and bring microscopy to schools across Oklahoma.
