Life and Episcopate
Born in Roman Greece in the first century, Eleuchadius was by training a Greek philosopher. The tradition of the Ravennate church holds that he was brought to the Christian faith through the preaching of Saint Apollinaris of Ravenna, a native of Antioch who, according to the same tradition, had accompanied the Apostle Peter to Rome before being sent to evangelize Ravenna.
Eleuchadius succeeded Saint Adheritus, the second bishop, to become the third bishop of Ravenna. He is traditionally assigned an episcopate running from approximately 100 to 112, and is said to have died at Ravenna in the latter year. In the local succession he was followed by Saint Marcian.
The early Christian records of Ravenna rest heavily on the Liber pontificalis ecclesiae Ravennatis, compiled in the ninth century by the historian Andreas Agnellus. That source contains confusions and conflations later corrected by scholars, and historical certainty diminishes for the earliest figures of the see; the dates attached to Eleuchadius are therefore traditional rather than firmly documented.
