De pictura (English: "On Painting") is a treatise or commentarii written by the Italian humanist and artist Leon Battista Alberti. The first version, composed in Latin in 1435, was not published until 1450. It is one of his three treatises on art; the other two are De statua and De re aedificatoria, that would form the Renaissance concept for the fine arts: painting, sculpture, and architecture.
