From the severity of manners, however, one evil arose—the single slave was sometimes condemned by vanity to carry the burden of two; and as their grumblings were proportioned to their hardship, their case was soon taken up by the comic poets, not, I fear, so much for the sake of humanity, as because it often furnished them with a good joke or two. By degrees, as no writers dwell so constantly on a fruitful topic or so frankly imitate each other, it became the fashion of the stage to introduce a miserable devil into every comedy, whose misfortunes, like those of the clown in our pantomimes, usually kept the theatre in a roar. The practice, however, had already grown stale in the time of Aristophanes, who both ridiculed and followed it; for while his sneers at the grumbling valet are repeated usque ad nauseam, much of the humour and interest of the Frogs arise out of the tricks and adventures of a melancholy wag of this description as Casaubon[155] long ago observed. ----- Footnote 155: Ad. Theoph. Char. p. 248. ----- When men have usurped an undue dominion over their fellows, they seldom know where to stop. The Syrians themselves, enslaved politically, and often sold into servitude abroad, affected when rich a peculiarly luxurious manner: female attendants waited on their ladies, who, when mounting their carriages, required them to crawl on all-fours that they might make a foot-stool of their backs.[156] ----- Footnote 156: Montaigne, Essais, iv. 224.

If we now pass from the consideration of slavery in the comparatively mild form which it assumed in Attica to an examination of the state of the Laconian Helots, we shall discover the spirit which actuated the two governments to present a still broader contrast in this, the lowest stage of its influence, than when operating upon the nobler citizens on the great arena of public life. Among certain scholars on the continent it appears to be very much the fashion to oppose an invincible scepticism to the testimony of ancient writers, as often as that testimony makes against any theory they desire to establish; and on the subject of the Helots several of the ablest authors among them have adopted an opinion which cannot be supported without annihilating several Greek authors, who, in their opinion, prophesy as awkwardly as Calchas did for the peace of Agamemnon. Among these the principal is Mr. Müller, from whom I have the misfortune to differ on many points, but without in the least disparaging his ability or his learning, for both of which I entertain the highest respect.[157] ----- Footnote 157:
