In the book I am currently writing, I want to follow a passage from Cornelius Nepos with a quote from Nietzsche preceded by a very brief explanation. It goes as follows:

Cornelius Nepos - "In him, Nature seems to have tested her creative ability; for it is agreed among all who have written concerning him, that no one was ever more remarkable than he, either for vices or virtues. Born in a most distinguished city, of a very high family, and by far the most handsome of all the men of his age, he was qualified for any occupation, and abounded in practical intelligence. He was eminent as a commander by sea and land; he was eloquent, so as to produce the greatest effect by his speeches; for such indeed was the persuasiveness of his looks and language, that in oratory no one was a match for him. He was rich, and, when occasion required, laborious, patient, liberal, and splendid, no less in his public than in his private life; he was also affable and courteous, conforming dexterously to circumstances. As soon as he relaxed and no pressing task occupied his mind, this same man was found to be extravagant, negligent, licentious, and lacking in self-restraint, so that all marveled at the presence of so much inconsistency and such a self-contradictory nature in a single human being". Of such internal ideological struggles, followed by the emergence of outstanding characters embracing them, Friedrich Nietzsche remarked"...then arise those delightfully amazing and unimaginable people, those enigmatic men predestined for victory and temptation, whose most beautiful expressions are Alcibiades and Caesar".

Here is the full page from Beyon Good and Evil:

The man from an age of dissolution, which mixes the races all together, such a man has an inheritance of a multiple ancestry in his body, that is, conflicting and frequently not merely conflicting drives and standards of value which war among themselves and rarely give each other rest — such a man of late culture and disturbed lights will typically be a weaker man. His most basic demand is that the war which constitutes him should finally end. Happiness seems to him, in accordance with a calming medicine and way of thinking (for example, Epicurean or Christian), principally as the happiness of resting, of having no interruptions, of surfeit, of the final unity, as the “Sabbath of Sabbaths,” to use the words of the saintly rhetorician Augustine, who was himself such a man. But if the opposition and war in such a nature work like one more charm or thrill in life — and bring along, in addition to this nature’s powerful and irreconcilable drives, also the real mastery and refinement in waging war with itself, and thus transmit and cultivate self-ruling and outwitting of the self, then arise those delightfully amazing and unimaginable people, those enigmatic men predestined for victory and temptation, whose most beautiful expressions are Alcibiades and Caesar (— in their company I’d like to place the first European, according to my taste, the Hohenstaufer Frederick II), and, among artists, perhaps Leonardo da Vinci.8 They appear precisely in the same ages when that weaker type, with its demands for quiet, steps into the foreground: both types belong with one another and arise from the same causes.

My question is, did I inserted the quote properly? Was my interpretation adequate? "Of such internal ideological struggles, followed by the emergence of outstanding characters embracing them, Friedrich Nietzsche remarked..."
