Saint Philonides was bishop of Curium during the early Christian years. In the Synaxarium of Constantinople his memory is celebrated on August 30. It states that Philonides, bishop of Curium found martyrdom during the reign of emperor Diocletian, at the beginning of the fourth century. He found martyrdom along with three other Christians, Aristoklis, Dimitrianos and Athanasios.
In the Synaxarium of Nicodemus it is also stated that Philonides, bishop of Curium, found a martyr's death, but his memory is indicated as been celebrated on June 17 and not the 30th of August.
In the Synaxarium of Nicodemus it is stated that Philonides chose death, when informed of the killing of the other three martyrs and learned that the Gentiles had been ordered to attack the Christians in obscene ways, such as rape. In order to avoid this shame he went to a cliff, prayed, and jumped into the empty space, setting his own life into an end. Shortly after his death, according again to the same Synaxarium, the saint appeared as a vision to two travelers, naked, bathed in perfume, holding a palm branch and having a crown on his head. The vision led the two men to the spot where the dead body of the saint was lying. However, the Gentiles took the saint's body and threw into the sea in order to disappear. But the sea washed the corpse on the shore from where eventually the Christians took it and buried it with honors.
Philonides is the first known bishop of Curium (late third and early fourth century). His death is placed in the period between 303 -305.
