The François Zola Dam

The François Zola Dam at Museum Wales in Cardiff depicts the infrastructure that bore the name of his closest childhood friend's father. François Zola, a hydraulic engineer of Italian birth, had designed and built the dam on the Arc river above Aix-en-Provence in the 1840s, supplying the city's water supply and creating a lake that partially flooded the landscape Cézanne would later paint obsessively. Émile Zola — François's son — had been Cézanne's companion and supporter from childhood through the 1870s; their eventual rupture, prompted by Zola's 1886 novel L'Oeuvre in which a fictional Cézanne-like painter fails tragically, was one of the most painful events of Cézanne's personal life. Painting the dam named after his friend's father carried emotional charge that the technical subject might not otherwise suggest. Museum Wales's acquisition of this unusual subject connects Welsh national collecting to the specific biographical landscape of French Post-Impressionism.

The geometric forms of the dam's masonry — its curved face, its straight top edge — provide an unusual degree of architectural structure in Cézanne's landscape. He uses this geometry as an anchor for the more loosely organized natural elements — rock, water, vegetation — that surround it, creating a tension between the human-made and the natural.
