"To see him," says Montaigne, "pick out a light action in a man's life, or a word, that does not seem to be of any importance, is itself a whole discourse." He even condescends to inform us of such homely particulars as that Alexander carried his head affectedly on one side; that Alcibiades was a dandy, and had a lisp, which became him, giving a grace and persuasive turn to his discourse; that Cato had red hair and gray eyes, and was a usurer and a screw, selling off his old slaves when they became unfit for hard work; that Caesar was bald and fond of gay dress; and that Cicero [19like Lord Brougham] had involuntary twitchings of his nose.
Such minute particulars may by some be thought beneath the dignity of biography, but Plutarch thought them requisite for the due finish of the complete portrait which he set himself to draw; and it is by small details of character--personal traits, features, habits, and characteristics--that we are enabled to see before us the men as they really lived.

Plutarch's great merit consists in his attention to these little things, without giving them undue preponderance, or neglecting those which are of greater moment.

Sometimes he hits off an individual trait by an anecdote, which throws more light upon the character described than pages of rhetorical description would do.

In some cases, he gives us the favourite maxim of his hero; and the maxims of men often reveal their hearts.
Then, as to foibles, the greatest of men are not visually symmetrical.
Each has his defect, his twist, his craze; and it is by his faults that the great man reveals his common humanity.

We may, at a distance, admire him as a demigod; but as we come nearer to him, we find that he is but a fallible man, and our brother.
