Adrian was a Christian missionary who was martyred in 309 in Caesarea, in modern Israel, with a traveling companion named Eubulus.

The two were traveling to Caesarea to visit the Christian community there. The area was part of the Roman empire, which was persecuting Christians. When they reached the city gates, they were asked about the purpose of their travel. They frankly acknowledged that they had come to assist the Christian community in the city. They were immediately arrested, and the local governor had them scourged and thrown to the lions.

The relics of St. Adrian rest in the reliquary chapel in the Basilica.

St. Adrian, you left your home to support persecuted Christians, and were martyred for your faith—pray for us!
