interior design and interior decoration. The concepts that were presented in his The Romantic Agony have been shaped into his design and art criticism. This writing style has been successfully employed in Praz's two most noteworthy design books, The House of Life and An Illustrated history in Interior Design. These works highlight his theories of the interiority of a space, and reveal his concepts of how a person inhabits the interior and how they shape it to make it their own. His ground-breaking work Studies in seventeenth-century imagery, first published in 1939 and reissued many times since, is one of the first attempts to produce a systematic catalogue and analysis of the early modern allegorical genres of the emblem and the personal device. Design writings Praz has had a profound impact not only on writings about interior design and decoration but also on the history, and the development, of design. The work, An Illustrated History of Interior Decoration from Pompeii to Art Nouveau has allowed the creation of a photographic album to be made, "Praz's rediscovery of this minor but fascinating art . . . was a revelation, and the historic no less than aesthetic importance of the subject is now recognised by a group of informed collectors". His work "provides a selection of visual representations of domesticity from ancient Greece through to the Art Nouveau, and a commentary upon them." The images show the interior decor and design of Greek, Roman, Medieval, Renaissance and Victorian Homes in Europe between the period of 1770 and 1860. The sketches, paintings, and watercolour representations capture the spatial qualities and features of the interiority and decoration of the overall space. The images record accuracy to the shape of the room, from the carpet, to the furniture, pictures, fabrics, wall colour, the hang of curtains and the placement of light. Praz's work has documented all these interior characteristics that would have shaped the space for the residents in the eighteenth and nineteenth centuries. This work has had a strong contribution to the impact of not only researching the interiority of a space, but provided a new groundwork into recording a history of an interior. Further, Praz has made an influential impact on the way interior design has been studied and documented since the mid twentieth century. He helped foster the change in the growth of historical design studies and research. His work, An Illustrated
