“Why would I tie myself to one woman?” asks Jerôme in Claire’s Knee, though he plans to marry a diplomat’s daughter by summer’s end. He spends his July at a lakeside boardinghouse, nursing crushes on the sixteen-year-old Laura and, more tantalizingly, her long-legged, blonde, older half sister, Claire. Baring her knee on a ladder under a blooming cherry tree, Claire unwittingly incites a moral crisis for Jerôme while creating an image that is both the iconic emblem of Eric Rohmer’s Six Moral Tales and one of French cinema’s most enduring moments.
