I hadn't intended to put up another fine art post so soon but I'm too sleepy to write something original and these Rubens drawings really are worth seeing. Be sure to click to enlarge.
The picture of the young girl above is from 1630 or so, done in red and black chalk with a little red ink brushed in and with white chalk for corrections. This stands out even among Rubens' other drawings. The girl is a specific person. We can see how in real life she'd be riddled with flaws as we all are, and yet at the same time she exemplifies an ideal of grace, depth and intellect.
I may have posted this one before, I can't remember. It's a study for a picture showing Daniel in the Lion's den.
