The Roman province of Pontus is mentioned three times in the New Testament in the following passages:
There were residents of Pontus (among many other) present for the Day of Pentecost in Acts 2, the day on which the Gospel message of salvation through the resurrected Christ was preached for the first time: “Parthians and Medes and Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia” (Acts 2:9).
Paul’s dear friend and fellow-tentmaker Aquila, was from Pontus: “And he found a Jew named Aquila, a native of Pontus, having recently come from Italy with his wife Priscilla, because Claudius had commanded all the Jews to leave Rome” (Acts 18:2).
The Apostle Peter wrote the letter of 1 Peter to Christians in Pontus (and other Roman provinces): “Peter, an apostle of Jesus Christ, To those who reside as aliens, scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia. . .” (1 Pet. 1:1).
The coast of Pontus was colonized by the Greeks ca. 700 BC. Sinope was a major port city of Pontus located on the Black Sea. This is in Turkey’s territory today.
Diogenes, the Cynic philosopher (ca. 412 BC – 323 BC), was a famous resident of Sinope. He was notorious for carrying a lamp during the daytime in Athens, claiming to be looking for an honest man.
At the base of this statue is a plaque relating another legend about Diogenes and Alexander the Great.
Plutarch relates the story of what happened when Alexander sought out Diogenes at Corinth:
  And now a general assembly of the Greeks was held at the Isthmus, where a vote was passed to make an expedition against Persia with Alexander, and he was proclaimed their leader. Thereupon many statesmen and philosophers came to him with their congratulations, and he expected that Diogenes of Sinope also, who was tarrying in Corinth, would do likewise.  But since that philosopher took not the slightest notice of Alexander, and continued to enjoy his leisure in the suburb Craneion, Alexander went in person to see him; and he found him lying in the sun. Diogenes raised himself up a little when he saw so many persons coming towards him, and fixed his eyes upon Alexander. And when that monarch addressed him with greetings, and asked if he wanted anything, ‘Yes,’ said Diogenes, “stand a little out of my sun.”  It is said that Alexander was so struck by this, and admired so much the haughtiness and grandeur of the man who had nothing but scorn for him, that he said to his followers, who were laughing and jesting about the philosopher as they went away, “But verily, if I were not Alexander, I would be Diogenes.” (Plutarch’s Lives, Alexander, 14:1-3).
