[166] Byron said, also, that intermittent fevers came at last to be agreeable to him, on account of the pleasant sensation that followed the cessation of pain. [167] “One day I thought I heard very sweet harmonies in a dream. I awoke, and I found I had resolved the question of fevers: why some are lethal and others not--a question which had troubled me for twenty-five years” (_De Somniis_, c. iv.). “In a dream there came to me the suggestion to write this book, divided into exactly twenty-one parts; and I experienced such pleasure in my condition and in the subtlety of these reasonings as I had never experienced before” (_De Subtilitate_, lib. xviii. p. 915). [168] “Jewels in sleep are symbolical of sons, of unexpected things, of joy also; because in Italian _gioire_ means ‘to enjoy’ (_De Somniis_, cap. 21; _De Subtilitate_, p. 338). [169] Buttrini, _Girolamo Cardano_, Savona, 1884. [170] Bertolotti (_I Testamenti di Cardano_, 1888) has shown that this legend has no foundation. [171] “I shall live in the midst of my torments, and among the cares that are my just furies, wild and wandering; I shall fear dark and solitary shades, which will bring before me my first fault; and I shall have in horror and disgust the face of the sun which discovered my misfortunes; I shall fear myself, and, for ever fleeing from myself, I shall never escape.” [172] Brewster’s _Memoirs of Sir I.
