was the political enemy of the Athenian demos; the ally of the
Persian was feared by the conqueror, and every interest, military and
commercial, contributed to feed the passionate and jealous hate that
existed against a neighbour, too near to forget, too warlike to
despise. The thoughtful and profound policy of Themistocles resolved
to work this popular sentiment to ulterior objects; and urging upon a
willing audience the necessity of making suitable preparations against
Aegina, then the mistress of the seas, he proposed to construct a
navy, fitted equally to resist the Persian and to open a new dominion
to the Athenians.

To effect this purpose he called into aid one of the most valuable
sources of her power which nature had bestowed upon Athens.

VI. Around the country by the ancient Thoricus, on the road from the
modern Kerratia to the Cape of Sunium, heaps of scoriae indicate to
the traveller that he is in the neighbourhood of the once celebrated
silver-mines of Laurion; he passes through pines and woodlands--he
notices the indented tracks of wheels which two thousand years have
not effaced from the soil--he discovers the ancient shafts of the
mines, and pauses before the foundations of a large circular tower and
the extensive remains of the castles which fortified the neighbouring
town [33]. A little farther, and still passing among mine-banks and
hillocks of scoriae, he beholds upon Cape Colonna the fourteen
existent columns of the temple of Minerva Sunias. In this country, to
which the old name is still attached [34], is to be found a principal
cause of the renown and the reverses of Athens--of the victory of
Salamis--of the expedition to Sicily.

It appears that the silver-mines of Laurion had been worked from a
very remote period--beyond even any traditional date. But as it is
well and unanswerably remarked, "the scarcity of silver in the time of
Solon proves that no systematic or artificial process of mining could
at that time have been established." [35] It was, probably, during
the energetic and politic rule of the dynasty of Pisistratus that
efficient means were adopted to derive adequate advantage from so
fertile a source of national wealth. And when, subsequently, Athens,
profiting from the lessons of her tyrants, allowed the genius of her
free people to administer the state, fresh necessity was created for
wealth against the hostility of Sparta--fresh impetus given to general
industry and publi
