The importance of Collins as a city has been reinforced by its position as a center for small Asian and European travelers. There are two ports, Cenchreae on the east side of the strait linking Asia and Lechaeum on the west side of Italy, so both sides are called city. This is a small city with an area of only 4 square kilometers, as the passenger enters a more inland, more important city, but it provides a landing for a ship moving from east to west.
Collins is an ideal trading city with two ports, two ports in the Saronic Gulf and Corinthia Bay. Therefore, this city is one of the wealthiest cities in ancient Greece. Corinthians developed their own coins and asked traders to use them in their cities. Thebes is a powerful city state in Corinth and Northern Athens, and has always changed direction in various wars in Greece. During the Persian War, they first sent people to Themopyra Island to fight the Persians, but later they fought against Sparta and Athens, alluring an alliance with Zercus I of Persia. At different times of history, they formed an alliance with Athens against Sparta and then turned to Sparta to fight Athens.
At the request of the Corinthians, the Spartans summoned to the Spartans in 432 BC the members of the Peloponnesos alliance, especially those who complained about the Spartan Parliament to Athens. This discussion was attended by alliances and members of unwanted delegation from Athens. And they also requested to be a forum for discussion between Athens and Corinth. Thucydides warned Sparta that the Corinthians would condemn Sparta's inaction at this point, they would continue to be passive, and that they would soon find themselves escorted if the Athenian faction were active An alliance. In response, the Athenians reminded the Spartans of military success and opposition to the Persian record, warned them of the dangers of such a strong country, and eventually to Sparta for 30 years of peace To encourage arbitration.
In the discussion of Sparta, the Corinthians gave a brilliant explanation of the Athenian faction. Much of the Athenian formation point is like an arrow pointing directly to the character of Edepus. Corinthians say, "Athenians are always innovators and will soon be able to solve problems and execute quickly" (history 1.75). Edips has shown such qualities. When he saw what he should do, he has not had time to waste or spend thinking about the best way. If God shows that the murderer of Lieus must be punished in order to get rid of Thebe's plague, he will investigate. Like Athens, he enjoyed peace and tranquility in difficulties and activities (History.1.76) and wanted to participate in direct investigation.
