On October 21, 63 BC, Roman philosopher, politician, and orator Marcus Tullius Cicero presented evidence to the members of the Roman senate as proof that Lucius Sergius Catilina was preparing a conspiracy to overthrow the Roman Republic, and in particular the power of the aristocratic Senate. Actually, the Catilinarian Conspiracy is one of the best-documented episodes of ancient history. It was the attempted seizure of power at Rome by the disaffected aristocrat Catiline. Marcus Tullius Cicero, acting Roman consul during this time was able to suppress the conspiracy, but caused vehement controversies, because he had executed the ringleaders. Cicero's speeches to the senate and people during the crisis have become rather popular.
On August 17, 1586, German theologian, author, and mathematician Johann Valentin Andreae was born. He claimed to be the author of the Chymische Hochzeit Christiani Rosencreutz anno 1459 (1616, Strasbourg, the Chymical Wedding of Christian Rosenkreutz), one of the three founding works of Rosicrucianism, a philosophical secret society said to have been founded in late medieval Germany by Christian Rosenkreutz. Rosicrucianism holds a doctrine or theology "built on esoteric truths of the ancient past", which, "concealed from the average man, provide insight into nature, the physical universe and the spiritual realm."
