Seurat's,'La Grande Jatte' spelled the limits of petti-borgeoise modernity. For the previous 20 years, the Impressionists, led by the incomparably gifted, Manet, had attempted to make images describing this class, their appearance & behaviour. However,the Impressionists were bourgeoise & inevitably more aligned to their own class, and with the simultaneous rise of the dealer-critic system. Thus the steady sequence of shows, interviews & promotional literature issuing from managed,'creative' artists became the commonplace we experience in the arts today. The new class disappeared from Impressionist art when it was absorbed into the bourgeoise.Witness Monet's shrewd disavowal of the figure as he opted for his less offensive, touristy canon of landscapes. The detatchment of Manet's barmaid at the Follies, 1882,and the inanimate, even catatonic people in Degas's pictures of this period exemplify the new class. Clark argues that the emergence of this class was a product of the rebuilding of Paris by Baron von Haussmann. The old work centre of the city was guttered during the rejig, the trades & graves moved to new peripheries, and commercial entertainments, leisure & pleasure grew in their place to cater for this new white-collar mass public. The questionable role of prostitution is crucial to Clark's claims for this class and it is on this question that Manet is pre-eminent. This era announced the rise of capitalism and the spectacle society of which Clark is a major critical voice. Prodigious scholarship, marvellous insights, with fascinating, rarely reproduced 'secondary' art works to flesh out the theme; I can't think of a better way of teasing back the past to view the present.
