Hercule-Savinien de Cyrano de Bergerac (6 March 1619 – 28 July 1655) was a French dramatist and duelist. He is now best remembered for the works of fiction which have been woven, often very loosely, around his life story, most notably the 1897 play by Edmond Rostand. In these fictional works he is featured with an overly large nose; portraits suggest that he did have a big nose, though not nearly as large as described in Rostand's play and the subsequent works about him.
Research indicates that around 1640 he became the lover of Charles Coypeau d'Assoucy, a writer and musician, until around 1653, when they became engaged in a bitter rivalry. This led to Bergerac sending d'Assoucy death threats that compelled him to leave Paris. The quarrel extended to a series of satirical texts by both men. Bergerac wrote Contre Soucidas (an anagram of his enemy's name) and Contre un ingrat ("Against an Ingrate"), while D’Assoucy counterattacked with Le Combat de Cyrano de Bergerac avec le singe de Brioché, au bout du Pont-Neuf
The model for the Roxane character of the Rostand play was Bergerac's cousin, who lived with his sister, Catherine de Cyrano, at the Convent of the Daughter of the Cross As in the play, Bergerac did fight at the siege of Arras (1640), a battle of the Thirty Years' War between French and Spanish forces in France (though this was not the more famous final Battle of Arras, fought fourteen years later). One of his confreres in the battle was the Baron Christian of Neuvillette, who married Cyrano's cousin. However, the plotline of the play, Cyrano de Bergerac, involving Roxane and Christian is entirely fictional.
