Reading from the Synaxarion:

Erastus, Olympas, Rodion, Sosipater, Quartus, and Tertios, Apostles of the 70

Of these Saints, Olympas and Rodion became disciples of Peter, the chief Apostle, and came to Rome, where they were beheaded by Nero. The others reposed in peace, having become bishops: Sosipater of Iconium, Quartus of Beirut, and Erastus of Paneas, or Paneias (which was also called Caesarea of Philippi); Saint Erastus had been chamberlain of the city of Corinth (Rom.16:23).
