As Hugh Aldersey-Williams explores, all three were able to use positions within the orbit of the Sun King to advance their modern ideas about the world. more

The Ether Dreams of Fin-de-Siècle Paris

The Ether Dreams of Fin-de-Siècle Paris

Those who sipped or sniffed ether and chloroform in the 19th century experienced a range of effects from these repurposed anaesthetics, including preternatural mental clarity, psychological hauntings, and slippages of space and time.

Beast in the Blood: Jean Denis and the “Transfusion Affair”

Beast in the Blood: Jean Denis and the “Transfusion Affair”

During the late 1660s in Paris, transfusing the blood of calves and lambs into human veins held the promise of renewed youth and vigour. Peter Sahlins explores Jean Denis’ controversial experiments driven by his belief in the moral superiority of animal blood: a substance that could help redeem the fallen state of humanity. more

Picturing Pregnancy in Early Modern Europe

Picturing Pregnancy in Early Modern Europe

When the womb began to appear in printed images during the 16th century, it was understood through analogy: a garden, uroscopy flask, or microcosm of the universe.

After the passing of William James — philosopher, early psychologist, and investigator of psychic phenomena — mediums across the US began receiving messages from the late Harvard professor. Channelling these fragmentary voices, Alicia Puglionesi considers the relationship between communication, reputation, and survival after death. more

Marxist Astronomy: The Milky Way According to Anton Pannekoek

Marxist Astronomy: The Milky Way According to Anton Pannekoek

Can a person’s experiences on earth alter how they perceive the stars? Lauren Collee peers through the telescope of Anton Pannekoek, the Dutch astronomer whose politics informed his human approach to studying the cosmos. more

The Spiralist

The Spiralist

Why do helical seashells resemble spiralling galaxies and the human heart? Kevin Dann leads us into the gyre of James Bell Pettigrew’s Design in Nature (1908), a provocative and forgotten exploration of the world’s archetypal whorl. more

“The Mark of the Beast”: Georgian Britain’s Anti-Vaxxer Movement

“The Mark of the Beast”: Georgian Britain’s Anti-Vaxxer Movement

Ox-faced children, elderly women sprouting horns, and cloven minds — all features attributed to Edward Jenner’s vaccine against smallpox.

The Uncertain Heavens: Christiaan Huygens’ Ideas of Extraterrestrial Life

The Uncertain Heavens: Christiaan Huygens’ Ideas of Extraterrestrial Life

During the 17th century, as knowledge of the Universe and its contents increased, so did speculation about life on other planets. One such source, as Hugh Aldersey-Williams explores, was Dutch astronomer, mathematician, and inventor Christiaan Huygens, whose earlier work on probability paved the way for his very modern evaluation of what alien life might look like. more

Fungi, Folklore, and Fairyland

Fungi, Folklore, and Fairyland

From fairy-rings to Lewis Carroll’s Alice, mushrooms have long been entwined with the supernatural in art and literature. What might this say about past knowledge of hallucinogenic fungi? Mike Jay looks at early reports of mushroom-induced trips and how one species in particular became established as a stock motif of Victorian fairyland. more

“More Lively Counterfaits”: Experimental Imaging at the Birth of Modern Science

“Invisible Little Worms”: Athanasius Kircher’s Study of the Plague

“Invisible Little Worms”: Athanasius Kircher’s Study of the Plague

Living through the devastating Italian plague of 1656, the great polymath Athanasius Kircher turned his ever-enquiring mind to the then mysterious disease, becoming possibly the first to view infected blood through a microscope. While his subsequent theories of spontaneous generation and “universal sperm” were easily debunked, Kircher’s investigation can be seen as an important early step to understanding contagion, and perhaps even the very first articulation of germ theory. John Glassie explores. more
