Martyrdom
According to the synaxarion, Apollonius came from Sardis in Lydia and declared himself a Christian, for which he was arrested. The authorities demanded that he take an oath by the name of the reigning emperor; he refused, saying that it was improper to swear by the name of a mortal man.
He was tortured at length and then crucified. The accounts associate his death with the city of Iconium and assign it to one of the third-century persecutions of Decius or Valerian, though they do not specify which with certainty.
