The calumnius letter of Peter IV of Aragon to pope Urban VI (September 11, 1380), with which the king requests that Atumano be replaced as archbishop of Thebes:

Most holy Father: We are assured that owing to the machinations and efforts of the archbishop of the city of Thebes - which, together with other cities, castles, and places in the duchies of Athens and Neopatras now belong to our dominion - the said city was captured by our enemies, and even now is being held by them on the advice of the archbishop himself. As a result of this, evils and scandals without number have occured in the said duchies, and there is no doubt that on this account the archbishop himself has sinned against the Church of God and against our royal Majesty. But this need not astonish us, for the archbishop was born in Constantinople, and his father was a Turk, his mother a schismatic [Greek], and while he was a Greek monk, because of terrible vices which we forbear even to mention on account of their enormity, in which vices [Simon Atumano] still persists, he would have been burned at the stake, had he not secretly removed himself to other parts, where parading himself as a man of honor with false representations, as experience now makes evident, he obtained the aforesaid archbishopric from the lord Pope Gregory XI. But, most clement Father, since it is repugnant to divine and human laws alike that such an evil man be sustained in so great a dignity, we humbly beseech your Holiness that it please you to deprive the archbishop, if thus he deserves to be called, of this dignity, for we could in no wise to allow him to reside in the said duchies.
