From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
To this he owed the power of living energetically in the present, undisturbed either by recollection or by expectation; to this he owed the capacity of acting at any moment with collected vigour, and of applying his whole genius even to the smallest and most incidental enterprise; to this he owed the many-sided power with which he grasped and mastered whatever understanding can comprehend and will can compel; to this he owed the self-possessed ease with which he arranged his periods as well as projected his campaigns; to this he owed the "marvellous serenity" which remained steadily with him through good and evil days; to this he owed the complete independence, which admitted of no control by favourite or by mistress, or even by friend.
It resulted, moreover, from this clearness of judgment that Caesar never formed to himself illusions regarding the power of fate and the ability of man; in his case the friendly veil was lifted up, which conceals from man the inadequacy of his working. Prudently as he laid his plans and considered all possibilities, the feeling was never absent from his breast that in all things fortune, that is to say accident, must bestow success; and with this may be connected the circumstance that he so often played a desperate game with destiny, and in particular again and again hazarded his person with daring indifference. As indeed occasionally men of predominant sagacity betake themselves to a pure game of hazard, so there was in Caesar's rationalism a point at which it came in some measure into contact with mysticism.
