Marginalia for Marginalia

That's an example of the way STC tended to jot down his Shakespeare thoughts (this particular one is in the British Library). It says:

This Play, which is Shakespeare’s throughout, is to me the most painful, say rather the only painful part of his genuine works. The comic and tragic parts equally border on the wanton, the one disgusting, the other horrible; and the pardon and marriage of Angelo not merely baffles the strong indignant claim of Justice (for cruelty, with lust and damnable Baseness, cannot be forgiven, because we cannot conceive them as being morally repented of) but it is likewise degrading to the character of Woman. Beaumont and Fletcher, who can follow Shakespeare in his errors only, have presented a still worse, because more loathsome and contradictory instance of the same kind in his Night-Walker, in the marriage of Alathe to Algripe. Of the counterbalancing Beauties of to Measure for Measure, I need say nothing; for I have already said, that it is Shakespeare’s throughout. S. T. Coleridge

But never mind the content: isn't it a striking piece of visual art? A kind of calligraphic Rothko.
