Frontispiece to Elémens de la philosophie de Newton

In the frontispiece to Voltaire's interpretation of Isaac Newton's work, Elémens de la philosophie de Newton (1738), Voltaire sits translating the Principia and his manuscript is illuminated by seemingly divine light coming from Newton himself, reflected down to Voltaire by Émilie du Châtelet who actually translated the work and collaborated with Voltaire to make sense of it.
