Cezanne’s Picnic on a Riverbank (1873-1874) is a partie de campagne that may be a vague allusion to Manet’s Luncheon on the Grass (1863)
A trio of two men and a woman congregate on the riverbank. The woman sits alone, hat off, her parasol between her legs. A man next to her holds a fishing pole. Another man stands with hands in his pockets, and behind him, another mannish figure (in long pants) is sleeping on the ground under a tree in the background. There is a basket with wine.
The day is perfect, with blue sky, white clouds, and leafy trees. Perhaps the parasol symbolizes that the woman is a prostitute, suggesting this is a lover’s tryst. Tissot uses similar parasol symbolism for his painting Le Partie Carrée (1870c.)
A bottle of wine is evident. Food is missing.
