The vehicle, however, has not formed the sole obstacle to those projectors:--the _viaticum_, especially the food, has been a difficulty not readily got over. Before Bishop Wilkins alludes to his flying chariot, he remarks, that even if men could fly, the swiftest of them would probably be half a year in reaching the end of his journey; and hence a problem would arise, "how it were possible to tarry so long without sleep or diet?" Of the former obstacle, however, he quickly disposes,--"seeing we do not then spend ourselves in any labour, we shall not, it may be, _need_ the refreshment of sleep: but if we do, we cannot desire a softer bed than the air, where we may repose ourselves firmly and safely as in our chambers"! Of the latter he finds somewhat more difficulty in disposing,--"and here it is considerable, that, since our bodies will then be devoid of gravity and other impediments of motion, we shall not at all spend ourselves in any labour, and so, consequently, not much need the reparation of diet, but may perhaps live altogether without it, as those creatures have done, who, by reason of their sleeping for many days together, have not spent any spirits, and so not wanted any food; which is commonly related of serpents, crocodiles, bears, cuckoos, swallows, and such like. To this purpose, Mendoca reckons up divers strange relations, as that of Epimenides, who is storied to have slept seventy-five years; and another of a rustic in Germany, who, being accidentally covered with a hay-rick, slept there for all the autumn and the winter following, without any nourishment Or, if we must needs feed upon something else, why may not smells nourish us? Plutarch, and Pliny, and divers other ancients, tell us of a nation in India, that lived only upon pleasing odours; and it is the common opinion of physicians, that these do strangely both strengthen and repair the spirits. Hence was it that Democritus was able, for divers days together, to feed himself with the mere smell of hot bread.[5] Or, if it be necessary that our stomachs must receive the food, why then it is not impossible that the purity of the etherial air, being not mixed with any improper vapours, may be so agreeable to our bodies, as to yield us sufficient nourishment," with many other arguments of the like nature. The Bishop ultimately, however, severs the knot, by the suggestion of his flying chariot, which he makes large enough (for, _ce n'est que le premier pas qui coute!_) to carry not only food for the _viaticum_ of the passengers, but also commodities for their traffic! Infinitely more ingenuity did the great comic poet of antiquity display, when he selected the _Scarabaeus;_ as the food which had already served the purposes of digestion with the Rider, was still capable of affording nutrition to the animal:-- [Greek: nun d'att'an autos kataphagoo ta sitia. toutoisi tois autoisi touton chortasoo[6]]
