Antique print titled 'La Vraije Methode pour les passades (.)'. Original old print of the Duke of Newcastle enacting half turns, canters and pirouettes on horseback. This print originates from the 1737 English edition of Cavendish's exposition on the theory and practice of equestrian dressage 'La Methode et Invention Nouvelle de Dresser les Chevaux'. William Cavendish, Duke of Newcastle, lost his fortune and title after the Battle of Marston Moor and went into exile on the continent. Whilst in Paris, he purchased eight Barbary horses, set up a manege and developed his own training methods.
