GUEVARA (Antonio de). L'Horloge des princes avec le tresrenomme livre de Marc Aurele. Paris, Nicolas Bonfons, 1580, In-8 (169 x 104 mm), soft vellum with covers (contemporary binding). In his idealised portrait of Marcus Aurelius, Guevara, preacher and historiographer to Charles V, portrays a prince imbued with stoicism and full of humanity. Guevara's works exerted a great influence throughout humanist Europe in the 16th century. A fine, well-preserved copy in contemporary vellum (some light marginal spotting, not serious).
