Countless visitors to Italy take up pencil and brush to record their impressions of the great masterpieces of Classical and Renaissance architecture. Some are architects themselves, some professional artists, but all are lovers of the light, the dust of Venice, Florence, Siena, and a half-dozen other stops on the Grand Tour. From the collections of the Royal Institute of British Architects, these twelve renderings convey the different approaches an artist might take, whether anatomizing a building, setting it in context, offering only a glimpse, celebrating the play of the sun on its tower, or suggesting how it might have looked the day after masons and carpenters had finished their work.
