According to later reports, he had a vision of the Virgin Mary standing beside Dominic and after the sermon she approached Tancred and beseeched him to "follow that man; and do not depart from him."
According to Jordan, it was unknown if he was alive or dead, but at the insistence of Tancred, Dominic prayed to God for the boy's life and he was miraculously healed.
At Tancred's urging, it is Stephen who prays to God and receives a miracle: the boy, dead, is brought back to life.
In 1222, after the death of Dominic the previous year, Tancred left Italy for the Holy Land as the superior of a group of friars, appointed by Jordan of Saxony to establish a mission there.
The Dominican historian and hagiographer Gregory Lombardelli, wrote the first biography of Tancred, Vita de Tancredo Tancredi.
