To the moderate faction of the Calixtine party belonged also Peter of Mladenovič, who has already been mentioned as one of the companions of Hus on his fatal journey to Constance. He wrote a Latin work entitled _Relatio de Magistri Joannis Hus causa_, which has been edited by Palacký, and contains a full account of Hus's journey to Constance, his imprisonment, and his death. This work--from which I have quoted in the last chapter--was very precious to the Hussites. Up to the time of the suppression of the National Church of Bohemia in the seventeenth century, it was customary in the Utraquist Church services to read a portion of the narrative of Mladenovič instead of the evangel on July 6, the anniversary of the "martyrdom" of Hus. Mladenovič also wrote a shorter Bohemian account of the sufferings of Hus. He died in 1451 as administrator of the consistory of the Utraquist Church. Of the more advanced writers of the Calixtine or Utraquist Church, Magister Jacobellus of Mies (or Střibro) is the most prominent. He became, immediately after the death of Hus, the leader of that party which adhered most closely to his teaching. He had already, during the captivity of his master, maintained the necessity of communion in two kinds, a doctrine which Hus had sanctioned in one of his letters.[54] Like most Bohemian divines of his time, Jacobellus wrote a Latin _Postilla_, as well as numerous other polemical treatises, both Latin and Bohemian. Some Bohemian hymns written by him have also been preserved, Jacobellus is, however, most worthy of notice as being the principal author of the celebrated _Articles of Prague_, that played so important a part in Bohemian history. After this event we find little mention of Jacobellus, and he died in retirement in 1429. Closely connected with Jacobellus is his friend the Englishman, Peter Payne,[55] whose name has already been mentioned. I have here no space to sketch out his adventurous career. He was obliged to fly from England, no doubt as being an adherent of Wycliffe, and settled in Bohemia, obtaining, in 1417, the degree of Master of Arts at the University of Prague. He belonged, like Jacobellus, to the more advanced Utraquists; and when the ideas of Přibram gained ground in that Church, even joined the Taborites. Peter Payne was also one of the Bohemian envoys at the Council of Basel, where he was occasionally in violent conflict with his countrymen, the English bishops. Though living so long in Bohemia, Magister Engliš appears never to have thoroughly mastered the language of the country. It is at least certain that when challenged by Magister Přibram to a public theological disputation in that language, Peter was obliged to decline. Some religious treatises, written in Latin, in which Payne defends the teaching of Wycliffe, have been preserved. He appears toward the end of his life to have cast his lot entirely with the men of Tabor, and was still living in that town in 1452.
