appearances which are supposed to beset and to seduce all insulated wanderers. Everybody knows the superstitions of the ancients about the _Nympholeptoi_, or those who had seen Pan. But far more awful and gloomy are the existing superstitions, throughout Asia and Africa, as to the perils of those who are phantom-haunted in the wilderness. The old Venetian traveller Marco Polo states them well: he speaks, indeed, of the Eastern or Tartar deserts; the steppes which stretch from European Russia to the footsteps of the Chinese throne; but exactly the same creed prevails amongst the Arabs, from Bagdad to Suez and Cairo--from Rosetta to Tunis--Tunis to Timbuctoo or Mequinez. 'If, during the daytime,' says he, 'any person should remain behind until the caravan is no longer in sight, he hears himself unexpectedly called to by name, and in a voice with which he is familiar. Not doubting that the voice proceeds from some of his comrades, the unhappy man is beguiled from the right direction; and soon finding himself utterly confounded as to the path, he roams about in distraction until he perishes miserably. If, on the other hand, this perilous separation of himself from the caravan should happen at night, he is sure to hear the uproar of a great cavalcade a mile or two to the right or left of the true track. He is thus seduced on one side: and at break of day finds himself far removed from man. Nay, even at noon-day, it is well known that grave and respectable men to all appearance will come up to a particular traveller, will bear the look of a friend, and will gradually lure him by earnest conversation to a distance from the caravan; after which the sounds of men and camels will be heard continually at all points but the true one; whilst an insensible turning by the tenth of an inch at each separate step from the true direction will very soon suffice to set the traveller's face to the opposite point of the compass from that which his safety requires, and which his fancy represents to him as his real direction. Marvellous, indeed, and almost passing belief, are the stories reported of these desert phantoms, which are said at times to fill the air with choral music from all kinds of instruments, from drums, and the clash of arms: so that oftentimes a whole caravan are obliged to close up their open ranks, and to proceed in a compact line of march.' Lord Lindsay, in his very interesting travels in Egypt, Edom, &c., agrees with Warton in supposing (and probably enough) that from this account of the desert traditions in Marco Polo was derived Milton's fine passage in Comus:-- 'Of calling shapes, and beckoning shadows dire, And aery tongues that syllable men's names On sands, and shores, and desert wildernesses.'
