descriptions of them, that the fore-part was open to the keel: they had a
mainsail, and were rowed by oars. Greece is so admirably situated for
maritime and commercial enterprize, that it must have been very early
sensible of its advantages in these respects. The inhabitants of the isle

distinguished for their intelligence and success in maritime traffic: soon
after the return of the Heraclidæ they possessed considerable commerce, and
for a long time they are said to have held the empire of the adjoining sea.
Their naval power and commerce were not utterly annihilated till the time
of Pericles.

The Corinthians, who are not mentioned by Homer as having engaged in the
Trojan war, seem, however, not long afterwards, to have embarked with great

are said to have first built vessels with three banks of oars, instead of
galleys.

Although the Athenians brought a considerable force against Troy, yet they
did not engage in maritime commerce till long after the period of which we

Of the knowledge which the Greeks possessed at this time, on the subject of

as depicting the countries of the globe; on it the earth was figured as a
disk surrounded by the ocean; the centre of Greece was represented as the
