Giacomo Girolamo Casanova was an Italian adventurer and author from the Republic of Venice. His autobiography, Histoire de ma vie, is regarded as one of the most authentic sources of the customs and norms of European social life during the 18th century.
As was not uncommon at the time, Casanova often used pseudonyms, the most frequent being Chevalier de Seingalt. He also published abundantly in French under the name Jacques Casanova de Seingalt.
He has become so famous for his often complicated and elaborate affairs with women that his name is now synonymous with "womanizer". He associated with European royalty, popes and cardinals, along with luminaries such as Voltaire, Goethe and Mozart. He spent his last years in Bohemia as a librarian in Count Waldstein's household, where he also wrote the story of his life.
As for myself, I always willingly acknowledge my own self as the principal cause of every good and of every evil which may befall me; therefore I have always found myself capable of being my own pupil, and ready to love my teacher.
