Honoré de Balzac,
The Works of Honoré de Balzac: About Catherine de' Medici…
“ Almost all the early Medici had natural children, whose lot was in every case splendid. The Cardinal Giulio de' Medici, Pope Clement VII., was the illegitimate son of Giuliano I. Cardinal Ippolito de' Medici was also a bastard, and he was within an ace of being Pope and head of the family.Certain inventors of anecdote have a story that the Duke of Urbino, Catherine's father, told her: "A figlia d'inganno non manca mai figliuolanza" (A clever woman can always have children, à propos to some natural defect in Henri, the second son of François I., to whom she was betrothed) . ”
