On its surface, the work of Regina Gimenez involves an aesthetic exploration of geometry and colour. Yet it is forged from the observation of what can be described as “subaltern” teaching forms, reflecting an interest in what she calls “popular knowledge”: teaching models based not so much on the established canons but on fictitious registers and domestic resources. This exhibition catalogue delves into the dialogue created between Gimenez and a specific work by Sonia Delaunay (1885–1979), ‘Costume de Sport’, a watercolour which she produced in 1925. As this stimulative meeting shows, Delaunay’s work is and always has been a reference for that of Gimenez.
