Gerard or Gérard Lairesse was a Dutch Golden Age painter and art theorist. His broad range of skills included music, poetry, and theatre. De Lairesse was influenced by the Perugian Cesare Ripa and French classicist painters such as Charles le Brun, Simon Vouet and authors such as Pierre Corneille and Jean Racine. His importance grew in the period following the death of Rembrandt. His treatises on painting and drawing, Grondlegginge Ter Teekenkonst, based on geometry and Groot Schilderboek, were highly influential on 18th-century painters.
