“Few men have had their elasticity so thoroughly put to the proof as Caesar-- the sole creative genius produced by Rome, and the last produced by the ancient world, which accordingly moved on in the path that he marked out for it until its sun went down. Sprung from one of the oldest noble families of Latium--which traced back its lineage to the heroes of the Iliad and the kings of Rome, and in fact to the Venus-Aphrodite common to both nations--he spent the years of his boyhood and early manhood as the genteel youth of that epoch were wont to spend them. He had tasted the sweetness as well as the bitterness of the cup of fashionable life, had recited and declaimed, had practised literature and made verses in his idle hours, had prosecuted love-intrigues of every sort, and got himself initiated into all the mysteries of shaving, curls, and ruffles pertaining to the toilette-wisdom of the day, as well as into the still more mysterious art of always borrowing and never paying. But the flexible steel of that nature was proof against even these dissipated and flighty courses; Caesar retained both his bodily vigour and his elasticity of mind and of heart unimpaired. In fencing and in riding he was a match for any of his soldiers, and his swimming saved his life at Alexandria; the incredible rapidity of his journeys, which usually for the sake of gaining time were performed by night--a thorough contrast to the procession-like slowness with which Pompeius moved from one place to another-- was the astonishment of his contemporaries and not the least among the causes of his success. The mind was like the body. His remarkable power of intuition revealed itself in the precision and practicability of all his arrangements, even where he gave orders without having seen with his own eyes. His memory was matchless, and it was easy for him to carry on several occupations simultaneously with equal self-possession. Although a gentleman, a man of genius, and a monarch, he had still a heart. So long as he lived, he cherished the purest veneration for his worthy mother Aurelia (his father having died early); to his wives and above all to his daughter Julia he devoted an honourable affection, which was not without reflex influence even on political affairs. With the ablest and most excellent men of his time, of high and of humbler rank, he maintained noble relations of mutual fidelity, with each after his kind. As he himself never abandoned any of his partisans after the pusillanimous and unfeeling manner of Pompeius, but adhered to his friends--and that not merely from calculation--through good and bad times without wavering, several of these, such as Aulus Hirtius and Gaius Matius, gave, even after his death, noble testimonies of their attachment to him.”

Big Red Son, p. 9
Consider the Lobster (2007)
Context: Nor let us forget Vegas's synecdoche and beating heart. It's kitty-corner from Bally's: Caesar's Palace. The granddaddy. As big as 20 walmarts end to end. Real marble and fake marble, carpeting you can pass out on without contusion, 130,000 square feet of casion alone. Domed ceilings, clerestories, barrel vaults. In Caesars Palace is America conceived as a new kind of Rome: conqueror of its own people. An empire of self.

Context: The greatest men the world has produced have known but little. They had a few facts, mingled with mistakes without number. In some departments they towered above their fellows, while in others they fell below the common level of mankind.
