Eodem die sancti Bonifatii, Episcopi et Martyris; qui fuit beati Romualdi discipulus. Hic, a Gregorio Quinto, Romano Pontifice, ad praedicandum Evangelium in Russiam missus, ibi, cum per ignem transisset illaesus, Regemque ac populum baptizasset, a furente Regis fratre necatus est, atque sic optatam martyrii coronam accepit.
