Being a leading naval power as well as a rich commercial city enabled ancient Corinth to establish coloniesin Syracuse on the island of Sicily and on Corcyra (modern Corfu). These colonies served as trading posts for the richly ornamental bronze works, textiles, and pottery that Corinth produced.
Beginning in 582 BC, in the spring of every second year the Isthmian Games were celebrated in honor of the sea god Poseidon. The Doric Temple of Apollo, one of Corinth's major landmarks, was constructed in 550 BC at the height of the city's wealth.
Corinth was conquered by Philip II of Macedon in 338 BC, but it was named the meeting place of Philip's new Hellenic confederacy. After Philip was assassinated, Alexander the Great immediately came to Corinth to meet with the confederacy, confirm his leadership, and forestall any thoughts of rebellion. At the Isthmian Games of 336 BC, the Greeks chose Alexander the Great to lead them in war against the Persians.
Corinth was partially destroyed by the Romans in 146 BC, but in 44 BC it was rebuilt as a Roman city under Julius Caesar. Roman Corinth prospered more than ever before and may have had as many as 800,000 inhabitants by the time of Paul. It was the capital of Roman Greece, equally devoted to business and pleasure, and was mostly populated by freedmen and Jews.
The Apostle Paul visited Corinth in the 50s AD and later wrote two letters to the Christian community at Corinth (the books of 1 and 2 Corinthians in the New Testament). When Paul first visited the city (51 or 52 AD), Gallio, the brother of Seneca, was proconsul of Corinth.
Paul lived in Corinth for 18 months (Acts 18:1-18), working as a tentmaker and converting as many Jews and pagans as he could. Here he first became acquainted with Aquila and Priscilla, who became his fellow-workers.
