Martyrs Thyrsos Leukios, and Kallinikos

The Accounts of Their Martyrdom

The surviving accounts agree on the broad outline but diverge in detail. In the version followed by the Orthodox Church in America, Thyrsos is the catechumen and Leukios the baptized Christian; some Greek synaxaria reverse this, naming Thyrsos as already baptized and Leukios as the catechumen. Both traditions describe Leukios confronting the persecuting official and being executed after torture.

The tradition assigns to Thyrsos the most elaborate sufferings: he is said to have endured the dislocation of his limbs, the loss of his eyes, and the breaking of his teeth, yet to have remained steadfast. A recurring motif is that his death was repeatedly prevented by divine intervention. One account relates that, when he was placed in a wooden coffin to be sawn asunder, the saw could not penetrate the wood, after which he prayed and died peacefully. Kallinikos, by contrast, is uniformly said to have been beheaded with the sword.

Relics and Later Veneration

The tradition records that, near the end of the fourth century, the Emperor Flavian built a church dedicated to Saint Thyrsos in the vicinity of Constantinople and enshrined his relics there. By some accounts the relics were later carried westward to Spain, and Thyrsos came to be honored in the Mozarabic rite, where he was given a full liturgical office. His veneration thus extended well beyond Bithynia into the wider Christian world.
