This saint, a layman, should not be confused with the other St Basil of Ancyra, who was a priest (March 22).
Troparion — Tone 4
Your holy martyr Basil, O Lord, / Through his sufferings has received an incorruptible crown from You, our God. / For having Your strength, he laid low his adversaries, / And shattered the powerless boldness of demons. / Through his intercessions, save our souls!.
