Fortunio Liceti, Litheosphorus, sive, De lapide Bononiensi lucem (Udine, 1640)

Phosphorescent Rock, or, On the Light of the Bolognese Stone

Galileo studied the “Stone of Bologna” or “solar sponge,” produced by alchemists from calcining spar (barium sulfide), which glows in the dark. Galileo inferred from its cool luminescence that light is not the same as heat, but a distinct entity, contra Aristotle.

In this book the philosopher Liceti responded, adapting Aristotelian theory to accommodate the Bologna Stone. He sent a copy to Galileo which prompted a lengthy correspondence.

Wondertooneel: Women and Museums

Wondertooneel Learning Leaflet

What were women doing in the museum? 

Levinus Vincent, a wealthy Dutch merchant with ties to the East Indies, created a spectacular 'Chamber of Wonders' natural history museum in Haarlem. Visiting dignitaries admired his museum, including Peter the Great and King Charles III of Spain. The detailed depictions of interior spaces include figures of women engaged in a variety of activities. Museums such as Vincent's offered women opportunities for participation in the natural sciences as donors, collectors, discoverers, visitors, patrons, lecturers and curators. This OER explores the significance of women in these early museums.

How do art and travel benefit natural history? 

Maria Merian (1647-1717), skilled in both art and natural history, studied the relationships between flowers and insects. She conducted field expeditions around the world, carried out research in gardens and museums, and produced detailed sketches and beautiful paintings, and even bred insects to aid in her entomological investigations.
