"I wanted such a letter as yours, for I am very unwell. On Wednesday night I was seized with an intolerable pain from my temple to the tip of my right shoulder, including my right eye, cheek, jaw, and that side of the throat. I was nearly frantic, and ran about the house almost naked, endeavoring by every means to excite sensation in different parts of my body, and so to weaken the enemy by creating a diversion. It continued from one in the morning till half-past five, and left me pale and faint. It came on fitfully, but not so violently, several times on Thursday, and began severer threats toward night; but I took between sixty and seventy drops of laudanum, and sopped the Cerberus just as his mouth began to open. On Friday it only niggled, as if the chief had departed, as from a conquered place, and merely left a small garrison behind, or as if he had evacuated the Corsica, and a few straggling pains only remained. But this morning he returned in full force, and his name is Legion. Giant-fiend of a hundred hands, with a shower of arrowy death-pangs he transpierced me; and then he became a Wolf, and lay gnawing my bones! I am not mad, most noble Festus! but in sober sadness I have suffered this day more bodily pain than I had before a conception of. My right cheek has certainly been placed with admirable exactness under the focus of some invisible burning-glass, which concentrated all the rays of a Tartarean sun. My medical attendant decides it to be altogether nervous, and that it originates either in severe application or excessive anxiety. My beloved Poole, in excessive anxiety I believe it might originate. I have a blister under my right ear, and I take twenty-five drops of laudanum every five hours, the ease and spirits gained by which have enabled me to write to you this flighty but not exaggerating account." About the same time he writes to another friend, "A devil, a very devil, has got possession of my left temple, eye, cheek, jaw, throat, and shoulder. I can not see you this evening. I write in agony." Frequent reference is made in Coleridge's correspondence to his sufferings, from rheumatic or neuralgic affections, and the following letter, written in 1797, may possibly explain their origin:
