For radiation therapy, the nurse & technician drew little targets with a pen on my abdomen & hip, then used those diagrams to write inside my body with radiation. The metaphor of writing (or, since Derrida, ofÂ inscribing)Â for these professional, routine physical actions feels in retrospect vitiated as well as pompous. Oh, heâ€™s a professorâ€”he canâ€™t write about his treatment in plain terms. Itâ€™s not writing, then, though done with accuracy & precision. Both the pen strokes & the focusing & calibration of the photon beam. https://youtu.be/jSgnWfbEx1A The marker with which they drew the target left broad lines & was not cold to the touch during application. The mark, going on, felt slightly oily, not like an ordinary alcohol-based marker. Unlike the MRI, I felt nothing during the treatments themselves. (In the MRI I could actually feel warmth generated in my tissues as the magnets worked. The x-ray photons passed right through me--might as well have been neutrinos for all I could feel. But they had a noticeable effect on the tumor in the bone, shrinking it (I'm told) & thus relieving pressure & pain. My left hip is quite stiff but the back pain, especially while bending, has been reduced by ninety percent. And here is a picture of the back pain itself. I drew it while lying on my back at night with the lights out, not looking at the pen or the paper, a day or two before the radiation treatments began. Tonight, perhaps, I'll see if I can draw a picture of how that same area of my back feels now. I've been doing a lot of drawing, much of it abstract, but also trying to get down the branchings of the trees I see while lying in bed & looking out the window. And just now I'm feeling my way toward the fundamental difference / similarity between drawing & writing. What I'm doing now, using a keyboard, is very obviously writing, but when I scrawl a note using a pencil (whether a line of poetry or a note when the pharmacist calls about how to take a new drug) that feels a little bit like drawing. And then of course there is drawing: I look out the window & try to capture the curve of a branch. What, then, of a drawing like the one above? Done without looking but trying to catch the phenomenon of a specific pain? And what was the nurse doing in making marks on which to line up a beam of high-energy photons? Her marks contained very precise information. Were they writing or drawing? Finally, though we are far beyond the "picture theory" of language, even this writing done on a keyboard is a kind of drawing. I want you to see what I can barely see myself--for us to picture things together, with picture being a highly transitive & collaborative verb.
