Literature occupied him long and earnestly; but, while Alexander could not sleep for thinking of the Homeric Achilles, Caesar in his sleepless hours mused on the inflections of the Latin nouns and verbs.

He made verses, as everybody then did, but they were weak; on the other hand he was interested in subjects of astronomy and natural science.
While wine was and continued to be with Alexander the destroyer of care, the temperate Roman, after the revels of his youth were over, avoided it entirely.

Around him, as around all those whom the full lustre of woman's love has dazzled in youth, fainter gleams of it continued imperishably to linger; even in later years he had love-adventures and successes with women, and he retained a certain foppishness in his outward appearance, or, to speak more correctly, the pleasing consciousness of his own manly beauty.

He carefully covered the baldness, which he keenly felt, with the laurel chaplet that he wore in public in his later years, and he would doubtless have surrendered some of his victories, if he could thereby have brought back his youthful locks.

But, however much even when monarch he enjoyed the society of women, he only amused himself with them, and allowed them no manner of influence over him; even his much-censured relation to queen Cleopatra was only contrived to mask a weak point in his political position.( 1) Caesar was thoroughly a realist and a man of sense; and whatever he undertook and achieved was pervaded and guided by the cool sobriety which constitutes the most marked peculiarity of his genius.
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.
