The Invention of Pastel Painting describes the relatively sudden emergence in the later seventeenth century of sets of friable pastel sticks and a new artistic practice of painting in pastel. The author reconsiders the use of natural and fabricated drawing sticks as tools, firmly locating their use in the context of historical function. 'Artistic techniques have a social history; they are signs endowed with cultural meaning by society.'<BR>In considering the history of chalk and pastel, the author argues that the change is aesthetic, not formal, and is grounded in social function and technical response. She has drawn not only on artists' letters and accounts, documents, critical and theoretical writings, and, broadly, the secondary literature, but also on close visual examination and scientific analysis of selected chalk drawings and paintings in pastel, particularly those created between 1500 and 1750.
