Grand manner refers to an idealized aesthetic style derived from classicism and the art of the High Renaissance. In the eighteenth century, British artists and connoisseurs used the term to describe paintings that incorporated visual metaphors in order to suggest noble qualities. It was Sir Joshua Reynolds who gave currency to the term through his Discourses on Art, a series of lectures presented at the Royal Academy from 1769 to 1790, in which he contended that painters should perceive their subjects through generalization and idealization, rather than by the careful copy of nature. Reynolds never actually uses the phrase, referring instead to the "great style" or "grand style", in reference to history painting:
Originally applied to history painting, regarded as the highest in the hierarchy of genres, the Grand Manner came thereafter also to be applied to portrait painting, with sitters depicted life size and full-length, in surroundings that conveyed the nobility and elite status of the subjects. Common metaphors included the introduction of classical architecture, signifying cultivation and sophistication, and pastoral backgrounds, which implied a virtuous character of unpretentious sincerity undefiled by the possession of great wealth and estates.
