Although discredited by seventeenth-century scientists, temperament theory - which attributed human moods to the interaction of four distinct bodily fluids or 'humours' - was refashioned a century later to create a moral and physiological typology of social classes. This revival was the work of leading physiologists of the time, but the impact of their thinking extended far beyond medicine to embrace the history of ideas and, in particular, the representation of the human body in art. In this richly-illustrated book, Tony Halliday argues that matters of artistic representation were closely connected to medical and political discourses throughout the later eighteenth century, especially during the successive phases of the French Revolution. He explores the effects of the reworked theory of humours on visual representation, focusing on: the interaction of art and politics in debates about the visual portrayal of the 'new citizen' Antique notions of an ideal body and their transformation in contemporary art the concept of a new 'muscular' temperament, and its social, political and artistic implications the impact of certain works of art such as Bouchardon's statue of Cupid fashioning a bow from the club of Herculesand the unease they revealed in late eighteenth-century Europe about the relationship of character, appearance and occupation.

Portraits were the most widely commissioned paintings in 18th-century France, but most portraits were produced for private consumption, and were therefore seen as inferior to art designed for public exhibition. The French Revolution endowed private values with an unprecedented significance, and the way people responded to portraits changed as a result. This is an area which has largely been ignored by art historians, who have concentrated on art associated with the public events of the Revolution. Seen from the perspective of portrait production, the history of art during the Revolution looks very different, and the significance of the Revolution for attitudes to art and artists in the 19th century and beyond becomes clearer.
