RÃ©union de dames, Abraham Bosse, 17th century. A salon is a gathering of people under the roof of an inspiring host, held partly to amuse one another and partly to refine the taste and increase the knowledge of the participants through conversation. These gatherings often consciously followed Horace's definition of the aims of poetry, either to please or to educate. Salons, commonly associated with French literary and philosophical movements of the 17th and 18th centuries, were carried on until as recently as the 1940s in urban settings.
