Ancient Theories

The great scientists Louis Pasteur (1822-1893) and Joseph Lister (1827-1912) revolutionized medical practice in the 19th century. Pasteur's discovery of the cause of fermentation formed the basis of modern germ theory while Lister developed antiseptic surgical methods based on that. The book contains a description of the theory, and accounts of their work and experiments.

Given how bad some of Rome's emperors were, it's a testament to just how insane and reviled Caligula was that he is still remembered, nearly 2,000 years later, as the epitome of everything that could be wrong with a tyrant. The Romans had high hopes for him after he succeeded Tiberius in AD 37, and by all accounts he was a noble and just ruler during his first few months in power. But after that, he suffered a mysterious illness that apparently rendered him insane. Indeed, the list of Caligula's strange actions is long.
