‘On Kawara’s work, in all its simplicity and soberness, is an intriguing rendering of the ‘time’ phenomenon. He reduces the intangible, inconceivable dimension of time to a visible, ordered structure without forfeiting any of that infinity. His work is a gigantic time-machine, as it were, a kind of science fiction in which one can completely lose themselves.’
Karel Schampers, 'A Mental Journey in Time' in: Exhibition Catalogue, Rotterdam, Museum Boymans-van Beuningen, ON KAWARA: DATE PAINTINGS IN 89 CITIES, 1991, p. 200
