Xenophon, in his short Account of the Spartan Commonwealth, [1]
speaking of the Behavior of their young Men in the Streets, says,
There was so much Modesty in their Looks, that you might as soon have
turned the eyes of a Marble Statue upon you as theirs; and that in all
their Behaviour they were more modest than a Bride when put to bed
upon her Wedding-Night: This Virtue, which is always join'd to
Magnanimity, had such an influence upon their Courage, that in Battel
an Enemy could not look them in the Face, and they durst not but Die
for their Country.

Whenever I walk into the Streets of London and Westminster, the
Countenances of all the young Fellows that pass by me, make me wish my
self in Sparta; I meet with such blustering Airs, big Looks, and bold
Fronts, that to a superficial Observer would bespeak a Courage above
those Grecians. I am arrived to that Perfection in Speculation, that I
understand the Language of the Eyes, which would be a great misfortune
to me, had I not corrected the Testiness of old Age by Philosophy.
There is scarce a Man in a red Coat who does not tell me, with a full
Stare, he's a bold Man: I see several swear inwardly at me, without
any Offence of mine, but the Oddness of my Person: I meet Contempt in
every Street, express'd in different Manners, by the scornful Look,
the elevated Eye-brow, and the swelling Nostrils of the Proud and
Prosperous. The Prentice speaks his Disrespect by an extended Finger,
and the Porter by stealing out his Tongue. If a Country Gentleman
appears a little curious in observing the Edifices, Signs, Clocks,
Coaches, and Dials, it is not to be imagined how the Polite Rabble of
this Town, who are acquainted with these Objects, ridicule his
Rusticity. I have known a Fellow with a Burden on his Head steal a
Hand down from his Load, and slily twirle the Cock of a Squires Hat
behind him; while the Offended Person is swearing, or out of
Countenance, all the Wagg-Wits in the High-way are grinning in
applause of the ingenious Rogue that gave him the Tip, and the Folly
of him who had not Eyes all round his Head to prevent receiving it.
These things arise from a general Affectation of Smartness, Wit, and
Courage. Wycherly somewhere [2] rallies the Pretensions this Way, by
making a Fellow say, Red Breeches are a certain Sign of Valour; and
Otway makes a Man, to boast his Agility, trip up a Beggar on Crutches
