My books, at this epoch, if they did not actually serve to irritate the disorder, partook, it will be perceived, largely, in their imaginative and inconsequential nature, of the characteristic qualities of the disorder itself. I well remember, among others, the treatise of the noble Italian, Coelius Secundus Curio, “_De Amplitudine Beati Regni Dei;_” St. Austin’s great work, the “City of God;” and Tertullian’s “_De Carne Christi_,” in which the paradoxical sentence “_Mortuus est Dei filius; credible est quia ineptum est: et sepultus resurrexit; certum est quia impossibile est,_” occupied my undivided time, for many weeks of laborious and fruitless investigation. Thus it will appear that, shaken from its balance only by trivial things, my reason bore resemblance to that ocean-crag spoken of by Ptolemy Hephestion, which steadily resisting the attacks of human violence, and the fiercer fury of the waters and the winds, trembled only to the touch of the flower called Asphodel. And although, to a careless thinker, it might appear a matter beyond doubt, that the alteration produced by her unhappy malady, in the _moral_ condition of Berenice, would afford me many objects for the exercise of that intense and abnormal meditation whose nature I have been at some trouble in explaining, yet such was not in any degree the case. In the lucid intervals of my infirmity, her calamity, indeed, gave me pain, and, taking deeply to heart that total wreck of her fair and gentle life, I did not fail to ponder, frequently and bitterly, upon the wonder-working means by which so strange a revolution had been so suddenly brought to pass. But these reflections partook not of the idiosyncrasy of my disease, and were such as would have occurred, under similar circumstances, to the ordinary mass of mankind. True to its own character, my disorder revelled in the less important but more startling changes wrought in the _physical_ frame of Berenice—in the singular and most appalling distortion of her personal identity.
