This sketch of Women on the Rokin in Amsterdam was made by George Hendrik Breitner with pencil on paper. It’s all about the process, isn't it? I mean, look at these lines! They're so immediate, so searching. You can almost feel Breitner's hand moving across the page, trying to capture the essence of a bustling city scene. The marks are light, airy, but they build up to create a sense of depth and movement. I am drawn to the way he suggests forms rather than defines them, letting the blank space of the paper do some of the work. Take the figures, for example. They're just a few quick strokes, but they convey so much about their posture and their relationship to each other. And the buildings in the background are even more abstracted, reduced to a series of lines and planes that suggest their architectural structure. It reminds me a bit of some of Cy Twombly’s sketchbook works, where the act of drawing becomes a kind of meditation on form and space. It’s like Breitner is saying, "Here's a glimpse of something, but it's up to you to fill in the details."
