Olof Arborelius (1842-1915). Swedish painter.
He was an artist of scarce level but, as with so many other mediocre artists it happens to create a little masterpiece, then they do not make more, only one, but in the meantime "that masterpiece" exists and we cannot disregard it. A dam on the river, a dock, a fire, a house hidden in the thick of the trees; that's all, yet there is something in the extreme vividness of the colors, in the darkness coming, in the rapid and incisive brushstrokes, in its summary of the paint layer, which tell us: watch it carefully!
