Macedonia, and Philip expelled them: he paid great attention to the working
of the mines; and by employing persons well skilled in this and in refining
the ore, he rendered them so extremely valuable, that, according to ancient
authors, he obtained the empire of Greece principally by means of the
immense sums he drew from them, amounting annually, according to Diodorus,
to 1000 talents of gold. When the Romans reduced Macedonia, they expressly
forbade the inhabitants from working the mines of gold or silver, or
refining either of those metals; permitting them, however, to manufacture
any other metal.

The princes of Macedonia previous to Philip, the father of Alexander,
notwithstanding the great advantage for maritime affairs and commerce
afforded by the sea-coasts, bays, harbours, &c., neither practised nor
understood them: this arose in a great measure from their being continually
engaged in wars, or having their ports occupied or blocked up by the
maritime states of Greece. Philip was the first who freed his country from
these evils and inconveniences; but his thoughts were too intently and
constantly fixed on other objects to allow him to turn his attention to
maritime affairs or commerce. Alexander, as we have already seen, bestowed
much care on his fleet, while engaged in the conquest of Asia; and when he
died at Babylon, had formed the design of placing his fleets, in every port
of his dominions, on a regular and extensive scale. But the advantages of
Macedonia for commerce were neglected in the midst of his vast plans
elsewhere, and the Macedonians, at the period of his death, were still
inattentive to maritime affairs.

Philip, the antagonist of the Romans, of whose power and success he was not
only jealous but apprehensive, as soon as he resolved to engage in
hostilities with them, applied himself to maritime affairs. His
determination seems to have been fixed when he learnt that the Romans had
