[359] After Shelley's meeting with Byron in Switzerland in 1816, before they met again in Venice, there had been a lapse of two years bridged only by a not always pleasant correspondence relating to Allegra, Byron's natural daughter. Shelley occupied the unenviable position of mediator between him and Jane Clairmont, the child's mother. Yet when the two men met again in August, 1818, it was at first on the terms recorded in _Julian and Maddalo_. Byron's influence served as a stimulus to this and to other poems of the same period. By December of that year Shelley's opinion of Byron had changed; on the 22d, he wrote to Peacock of _Childe Harold_ in terms that show how quickly his views could alter: "The spirit in which it is written, is, if insane, the most wicked and mischievous insanity that was ever given forth. It is a kind of obstinate and self-willed folly, in which he hardens himself. I remonstrated with him in vain on the tone of mind from which such a view of things alone arises.... He (Byron) associates with wretches who seem to have lost the gait and physiognomy of man, and who do not scruple to avow practices, which are not only not named, but I believe seldom even conceived in England. He says he disapproves, but he endures. He is heartily and deeply discontented with himself; and contemplating in the distorted mirror of his own thoughts the nature and destiny of man, what can he behold but objects of contempt and despair? But that he is a great poet, I think the address to Ocean proves. And he has a certain degree of candour while you talk to him, but unfortunately it does not outlast your departure. No, I do not doubt, and for his own sake, I ought to hope, that his present career must soon end in some violent circumstance." (_Works of Shelley_, VIII, pp. 80-81.)
