decided on, it happened not unfrequently that the Magistri of Cracow spoke the word which turned the scale.
The opinion of the young Jagellonian school carried great authority with the powers of all Christendom in that period. The fame of some scholars spread far beyond the limit of their native country: Filelfo and Paul Vladimiri had taken a distinguished part in the Council of Constance; Jacobus a Paradiso, well known in Germany as a theologian, was one of the most ardent promoters of Church reorganization; Zaborowski and Elgot were famous decretists; so was Nicholas of Blonia, Sedziwoj Czechel (who was only active for a short time in the University), and later on, the excellent Latinist and theologian Gregorius of Sanok, a precursor of the classical Renascence.
