Smyrnae sancti Pionii, Presbyteri et Martyris; qui, post apologias pro fide Christiana conscriptas, post squalorem carceris, ubi multos fratrum ad martyrii tolerantiam suis exhortationibus roboravit, tandem, cruciatibus multis vexatus, clavis confixus et ardenti rogo superpositus, beatum pro Christo finem sortitus est. Cum ipso autem et alii quindecim passi siunt.
