Prolonged negotiations ensued; but finally a Hussite embassy, led by Prokop and including John of Rokycan, the Taborite bishop Nicolas of Pelhfimov, the "English Hussite," Peter Payne and many others, arrived at Basel on the 4th of January 1433.
The last-named, however, refused to recognize as archbishop of Prague, John of Rokycan, who had been elected to that dignity by the estates of Bohemia.
The Bohemian brethren, whose intellectual originator was Peter Chelcicky, but whose actual founders were Brother Gregory, a nephew of Archbishop Rokycan, and Michael, curate of Zamberk, to a certain extent continued the Taborite traditions, and in the 15th and 16th centuries included most of the strongest opponents of Rome in Bohemia.
Those who signed it pledged themselves to recognise the Compacts, and to support as archbishop of Prague, John of Rokycan, who had been chosen by the estates in accordance with an agreement made simultaneously with the Compacts, but whom the Church of Rome refused to recognize.
They further g Y renewed the demand, which they had already expressed at the diet of 1567, that the estates should have the right of appointing the members of the consistory - the ecclesiastical body which ruled the Utraquist church; for since the death of John of Rokycan that church had had no archbishop. After long deliberations and the king's final refusal to recognize the confession of Augsburg, the majority of the diet, consisting of members of the Bohemian brotherhood and advanced Utra quists, drew up a profession of faith that became known as the Confessio Bohemica.
A Bohemian work by Archbishop John of Rokycan has also been preserved; it is entitled Postilla and is similar though inferior to the work of Huss that bears the same name.
Among his other works his Postilla and polemical writings in the form of letters to Archbishop John of Rokycan and Bishop Nicolas of Pelhfimov deserve mention.
Most important are the Letters to Archbishop Rokycan and the book On good and evil priests.
In the interior of the church the tomb of the astronomer Tycho Brahe is notable, as is thevery ancient pulpit from which the Hussite archbishop John of Rokycan preached.
