Consider, for instance, the hierarchy of entities that go by the name of landscape: first, a specimen (say, a specific painting by John Constable); second, a genre (the whole class of things called landscape painting, with its specific history in Western painting and beyond); third, landscape considered as a medium, the actual countryside or lived space of a people, including the specific concrete place in the Stour valley where Constable lived and painted. The dialectics of species and specimen, stereotype and individual, class and member, image and picture cut across all these levels of attention. That is why landscape itself is such an ambiguous term, referring at once to the represented motif in a painting, the painting itself, and the genre to which it belongs."
