"Sept 29-53 (Fiesole)" is an abstract work by British artist Ben Nicholson from 1953, created during his time in the Tuscan hill town of Fiesole. The painting exemplifies Nicholson's distinctive style of geometric abstraction, featuring subtle interplays of pale tones, incised lines, and carefully calibrated rectangular forms that suggest both landscape and pure formal composition. The title's date notation reflects Nicholson's practice of precisely documenting his creative process while maintaining an ambiguous relationship between representation and abstraction.
