Strabo, Geography

Corinth is called "wealthy" because of its commerce, since it is situated on the Isthmus and is master of two harbors, of which the one leads straight to Asia, and the other to Italy; and it makes easy the exchange of merchandise from both countries that are so far distant from each other. And just as in early times the Strait of Sicily was not easy to navigate, so also the high seas, and particularly the sea beyond Maleae, were not, on account of the contrary winds; and hence the proverb, “"But when you double Maleae, forget your home."”Source unknown At any rate, it was a welcome alternative, for the merchants both from Italy and from Asia, to avoid the voyage to Maleae and to land their cargoes here. And also the duties on what by land was exported from the Peloponnesus and what was imported to it fell to those who held the keys. And to later times this remained ever so. But to the Corinthians of later times still greater advantages were added, for also the Isthmian Games, which were celebrated there, were wont to draw crowds of people. And the Bacchiadae, a rich and numerous and illustrious family, became tyrants of Corinth, and held their empire for nearly two hundred years, and without disturbance reaped the fruits of the commerce; and when Cypselus overthrew these, he himself became tyrant, and his house endured for three generations; and an evidence of the wealth of this house is the offering which Cypselus dedicated at Olympia, a huge statue of beaten gold.¹ Again, Demaratus, one of the men who had been in power at Corinth, fleeing from the seditions there, carried with him so much wealth from his home to Tyrrhenia that not only he himself became the ruler of the city² that admitted him, but his son was made king of the Romans.³ And the temple of Aphrodite was so rich that it owned more than a thousand temple slaves, courtesans, whom both men and women had dedicated to the goddess. And therefore it was also on account of these women that the city was crowded with people and grew rich; for instance, the ship captains freely squandered their money, and hence the proverb, “"Not for every man is the voyage to Corinth."”Source unknown Moreover, it is recorded that a certain courtesan said to the woman who reproached her with the charge that she did not like to work or touch wool: "Yet, such as I am, in this short time I have taken down three webs."⁴
