Paul and Barnabas visited the city of Salamis on the eastern coast of Cyprus during the First Missionary Journey. Salamis which rivalled Paphos on the western coast was a major commercial harbour for principle exports of the island such as copper and timber. There was a great Jewish community having more than one synagogue.
"when they arrived at Salamis, they proclaimed the word of God in the synagogues of Jews"
Paul and Barnabas preached the gospel to mainly to Jews while they crossed the island from east to west. Finally they arrived to Paphos. Paphos was the capital city of Roman rule in Cyprus and the center of the worship for Aphrodite, goddess of love and beauty. The city had evil reputation for laxity of morals.
In Paphos Paul and Barnabas met Roman Proconsul, Sergius Paulos who wanted to hear the word of God. A sorcerer called Elymas wanted to turn him away from his faith. But Paul blinded him temporally. Witnessing to what happened to Elymas, Sergius Paulos believed. From this point on Saul used this Roman name Paul.
