Anno 800. The day before Karl reached Rome pope Leo came to Nomentum to meet him. Karl received him with great honor and they dined together. The pope preceded Karl to Rome, and the next morning took his stand, with the bishops and all the clergy of the city, on the steps of St. Peter's to receive Karl when he should come. ... Seven days later Karl called a public meeting, in which he made known the reasons why he had come to Rome. He then devoted himself every day to the accomplishment of the things which had called him to the city. Of these he began with the most important as well as the most difficult, namely, the investigation of the crimes with which the pope was charged. As there was no one who was willing to prove the truth of those charges, Leo took the gospels in his hand, and, in the presence of all the people, mounted the pulpit in St. Peter's, and took an oath that he was innocent of the crimes laid to his charge. 49.

And now the most clement and serene king, Karl, has come with his priests and nobles to this city to try the case. Therefore, I, Leo, bishop of the holy Roman church, neither judged nor coerced by anyone, do clear and purge myself from these charges before you in the sight of God, who knows my secret thoughts, and of his holy angels, and of St. Peter, in whose church we now stand. I swear that I neither did these wicked and criminal things of which my enemies accuse me, nor ordered them to be done, and of this God is my witness, in whose presence we now stand and into whose judgment we shall come.
