Black Lines (1913), Vasily Kandinsky
Rank: 87
No one with any assurance can point to the first truly abstract painting in art history, but this one comes pretty close. It is, oddly, the result of deliberately slow product rollout, at least according to the Guggenheim. It turns out that well before he created this canvas, Kandinsky knew precisely where he wanted to go with respect to abstract, or non-objective, art, but he was concerned with public reaction. So in the paintings leading up to this one, he maintained tenuous connections to representation, before finally dispensing with them altogether here.—Howard Halle
