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."
On November 21, 1694, François-Marie Arouet was born, known by his nom de plume Voltaire, French philosopher during the Age of Enlightenment, re-known by his wits, prolific writer of novels, poems, essays, and letters, and dear friend of Prussian king Frederick the Great.
