The Tragic End of Milo of Croton

Milo of Croton was the strongest man in the ancient Greek world, or so the stories say. A six-time Olympic champion, military hero, and larger-than-life celebrity, he became the subject of countless legends. Yet despite his extraordinary feats of strength, Milo is remembered today as much for the bizarre manner of his death as for his victories. According to ancient writers, the man who could carry a bull on his shoulders met his end while attempting to split a tree apart with his bare hands.

The Ancient Underground Aqueducts of Siena

Underneath the narrow streets, churches, and palaces of the Italian city of Siena lies a sprawling network of underground aqueducts that supplied water to the Tuscan city for centuries, enabling it to flourish despite a chronic lack of nearby rivers and streams. Extending for roughly 25 kilometers, the so-called Bottini constitute an ingenious hydraulic system that sustained the city from the Middle Ages until the early 20th century.

Giovanni Battista Bugatti: The Papal Executioner of Rome

For nearly seven decades, one of the most feared men in Rome lived an otherwise ordinary life. He sold umbrellas, attended church, and walked the narrow streets of the Borgo district near the Vatican. Yet whenever he crossed the Tiber River, Romans knew that someone was about to die.

His name was Giovanni Battista Bugatti, though history remembers him by a different name: Mastro Titta.

John Michell: The Forgotten Genius Who Predicted Black Holes

More than a century before Albert Einstein revolutionized physics with his theory of general relativity, and nearly two centuries before astronomers accepted the existence of black holes, an English clergyman and scientist named John Michell proposed a startling idea. In 1783, Michell suggested that some stars might possess such immense gravity that even light could not escape from them. These invisible objects, which he called "dark stars," bear a remarkable resemblance to what we now know as black holes.

The Execution of Alchemist Georg Honauer

It appears that quite a few people have been killed or brought to justice for having failed to deliver on their promise of turning ordinary metals into gold, in other words, alchemy. One was the English chemist James Price, who took his own life after his deception was exposed. Another was Georg Honauer, whose downfall ended not in disgrace alone but in a spectacular public execution.

Georg Honauer was born in Olomouc, Moravia (now in the Czech Republic), in 1572. In 1596, he entered the service of Friedrich I, Duke of Württemberg, in Stuttgart after persuading the duke that he was both a skilled goldsmith and a successful alchemist.

Marcus Terentius Varro and The Invisible Creatures That Cause Disease

In the first century BC, nearly two thousand years before the invention of the microscope, the Roman scholar Marcus Terentius Varro made a remarkable observation about the cause of disease. Writing in his agricultural treatise De Re Rustica around 37 BC, Varro advised landowners to avoid building homes near swamps. His reason was unusual for the time:

There are bred certain minute creatures which cannot be seen by the eyes, which float in the air and enter the body through the mouth and nose and there cause serious diseases.

The statement sounds astonishingly similar to the principles of germ theory. Varro described invisible living organisms too small to be seen, entering the human body and causing illness. Although he lacked any means of observing microorganisms and had no scientific evidence to support his claim, his words represent one of the closest approaches to germ theory found in the ancient world.
