To this objection it may be replied, in the first place, that between the tropics (within which space nearly the whole of the navigation was performed) nine months is much too long a time to allow for each interval on shore, between the sowing and the reaping:  and, secondly, that though the period occupied by the whole voyage, and some of the circumstances attending it, may be inaccurately stated, the voyage itself ought not to be wholly discredited on these accounts.

The very circumstance which the historian rejects as incredible, is one of the strongest arguments possible in favour of the tradition; though this alone is not decisive, for the Phoenicians might have sailed far enough to the south to have observed the sun to the north, even if they had not accomplished the navigation of Africa.  The strongest argument, however, in our opinion, in support of the actual accomplishment of this circumnavigation, has been unaccountably overlooked, in all the various discussion to which the subject has given rise.  It is evident that in most voyages, false and exaggerated accounts may be given of the countries visited or seen, and of the circumstances attendant upon the voyage; whereas, with respect to this voyage, one most important and decisive particular lay within reach of the observation of those who witnessed the departure and arrival of the ships.  If they sailed from the Red Sea, and returned by the Mediterranean, they must have circumnavigated Africa.  It is obvious that if such a voyage was not performed, the story must have originated with Herodotus, with those from whom he received his information, or with those who were engaged in the expedition, supposing it actually to have been engaged in, but not to have accomplished the circumnavigation of Africa.  The character of Herodotus secures him from the imputation; and by none is he charged with it:—­Necho lived about six hundred and sixteen years before Christ; consequently little more than two hundred years before Herodotus; moreover, the communication and commerce of the Greeks with Egypt, was begun in the time of Psammeticus, the immediate predecessor of Necho, and was encouraged in a very particular manner by Amasis (who died in 525), who married a Greek, and was visited by Solon.  From these circumstances, it is improbable that Herodotus, who was evidently not disposed to believe the account of the appearance of the sun, should not have had it in his power to obtain good evidence, whether a ship that had sailed from the Red Sea, had returned by the Mediterranean:  if such evidence were acquired, it is obvious, as has been already remarked, that the third source of fabrication is utterly destroyed.  Dr. Vincent is strongly opposed to the authenticity of this voyage, chiefly on the grounds that such ships as the ancients had, were by no means sufficiently strong, nor their seamen sufficiently skilful and experienced, to have successfully encountered a navigation, which the Portuguese did not accomplish without great danger and difficulty, and that the alleged circumnavigation produced no consequences.
