His appointment as rector of a school at Buda was of no long continuance; his views excited the zeal of the Dominicans and he was thrown into prison.
This charge is denied by his apologists; and though his methods were attacked by good Catholics like Johann Hass, he was elected prior of the Dominicans in Glogau in i 505.
In the persecuting activity that ensued the Dominicans, "the Dogs of the Lord" (Domini canes), took the lead., Commissaries of the Holy Office were sent into different provinces, and ministers of the faith were established in the various cities to take cognisance of the crimes of heresy, apostasy, sorcery, sodomy and polygamy, these three last being considered to be implicit heresy.
His philosophical position was determined, or at least very greatly influenced, by the antagonism between the Dominicans and the Franciscans.
The Order of Dominicans grew out of the little band of volunteers that had joined Dominic in his mission among the Albigenses.
