To all and singular that shall see and hear these presents, I John de Clum do it to understand, how Master John Huss, bachelor of divinity, under the safe conduct and protection of the renowned prince and lord Sigismund of Romans, always Augustus, and king of Hungary, &c., my gracious lord; and under the protection, defence, and safeguard of the holy empire of Rome, having the letters patent of the said my lord, king of the Romans, &c., came unto Constance to render a full account of his faith in public audience, to all that would require the same. This the said Master John Iluss, in this imperial city of Constance, under the safe conduct of the said my lord, king of Romans, hath been and yet is detained. And although the pope with the cardinals have been seriously required by solemn ambassadors of the said my lord, king of Romans, &c., in the king's name and behalf, that the said Master John Huss should be set at liberty, and be restored unto me: yet notwithstanding they have and yet do refuse hitherto to set him at liberty to the great contempt and derogation of the safe conduct of the king, and of the safeguard and protection of the empire, or imperial majesty. Wherefore I John aforesaid, in the name of the king, do here publish and make it known, that the apprehending, and detaining of the said Master John Huss was done wholly against the will of the beforenamed king of Romans, my lord; seeing it is done in the contempt of the safe conduct of his subjects, and of the protection of the empire, because the said my lord was then absent far from Constance, and if he had been there present, would never have permitted the same. And when he shall come, it is to be doubted of no man, but that he, for this great injury and contempt of this safe conduct done to him and to the empire, will grievously be molested for the same.
Given at Constance, the day of the Nativity of the Lord, 1414.
In this instrument above prefixed, note, gentle reader! three things.
First, The goodness of this gentle lord John de Clum, being so fervent and zealous in the cause of John Huss, or rather in the cause of Christ.
Secondly, The safe conduct granted unto the said John Huss, under the faith and protection of the emperor, and of the empire.
Thirdly, Here is to be seen the contempt and rebellion of these proud prelates, in disobeying the authority of their high magistrate, who, contrary to his safe conduct given, and the mind of the emperor, did arrest and imprison this good man, before the coming of the said emperor, and before that John Huss was heard. Let us now, as we have promised, adjoin some of the epistles of this godly man:
