The Catholic Priest, Collegiate Canon
Stanley from Nasierowo was a Canon in Warsaw Collegiate (as we assume). According to Wislocki we know that Stanley was an owner of the book Decretum Gratiani or Concordia discordantium canonum, published in Basel (1486).[1]
Stanley from Nasierowo (Stanislaw de Nasirow) completed studies in philosophy at the Universitas Jagellonica Cracoviensis (Jagiellonian University founded in 1364):
Anno domini millesimo quadringentesimo sexagesimo nono, in decanatu Mgri Nicolai de Staw, ad Quatour tempora Lucie, infra scriptio ad gradum bacalaritus in artibus sunt promoti et secundum hunc ordinem locati: (…) Stanilslaw de Nasirow(s.68)
Anno domini millesimo quadringentesimo septuagesimo quarto, in decanatu Mgri Jacobi de Broxicze, licenciati medicine, sacre theologie baccalarij et canonici sancti Floriani, post festa Natiuitatis Christi, ad gradum magisterii promotii, hoc ordine sunt locati: (…) Stanislaw de Nasirow (s.75-76)
Translation from latin confirms that in 1469 Stanley from Nasierowo gained bachelor degree in philosophy. In 1474 he gained masters degree (magisterium) from Jagiellonian University.
