A painting that reveals (alethe) a whole world. Heidegger mentions this particular work of Van Gogh's in "The Origin of the Work of Art".
"Aletheia, disclosure thought of as the opening of presence, is not yet truth. Is aletheia then less than truth? Or is it more because it first grants truth as adequatio and certitudo, because there can be no presence and presenting outside of the realm of the opening?"
