Cerebral syphilis is an extraordinary thing. Besides causing general paralysis, which is known positively to be syphilitic, the disease acts upon the arteries of the brain, and the symptoms that it causes seem to depend upon the areas of the brain that the diseased arteries supply. If the affected area is the front of the brain in which the intellectual faculties are supposed to be, all the symptoms of violent mental irritation are caused. They may begin quite early in the disease, and may last for many years till the patient’s death; much appears to depend upon whether the patient has been able to live a decent and quiet life. That in the case of Henry VIII his disease apparently led to nothing more monstrous than cutting off two of his wives’ heads—possibly they deserved it—and to violent and murderous political activity, would rather seem to show that if he had had a chance of rest and treatment he might have been no worse a king than many others who have won fame and gratitude. At least he was a highly educated man who certainly meant well at first. Ivan from the beginning was little better than a brute, of shocking family history and evil impulses. In him it probably went far beyond the stage of mere syphilitic psychasthenia.[10] Seven wives in all were his, so that he beat Henry’s record by one. I suppose he showed the same miserable story of domestic unhappiness, but I have not been sufficiently interested to find out. Some of his letters are still extant, and they show all the signs of insanity, in their unwieldy length, their foolish cunning, their voluble avoidance of the main point, and their inconsequence. On the evidence of these letters alone any two doctors to-day would “sign up” Ivan IV. To say that he became wildly sexual would be to understate the matter: he developed the morals of a satyr. This is all very characteristic of syphilitic insanity, whose victims often find its worst effects in an utter abandonment of sexual restraint. It is almost as if the disease, being often the result of impurity, revenges itself on the victim by accentuating the very incontinence which has caused it. The rest of the story of Ivan the Terrible—it is strange that history has not yet called him Ivan the Great—is not very interesting, except for two shocking incidents that we shall relate in their turn. It is simply the record of a man with an Oriental mind, maddened by syphilis, abandoning himself to the most ruthless cruelty, experimenting as if to plumb the depths of human wickedness. It would be wearisome both to tell it and to read it, with all the senseless stabbings, the stamping on the feet of helpless menials, the red-hot pokers, the experiments in torture, the burnings, the infamy. Let us hold our noses and turn to historical facts of a broader interest.
