2. This refers to the café-restaurant run since 1867 by
Emmanuel Siron in Barbizon; most of their guests were painters. Siron called it the ‘Hôtel de l’exposition’, because there were always paintings on display. The establishment is now the Hôtellerie du Bas-Bréau, 22 Grande rue.
‘Mère Siron’ must refer to Emmanuel’s wife. See
