Adalper, episcopus Parentinus

Euphrasius, the bishop of Poreč, imposes a variety of taxes, including the tithe and the ecclesiastical quartese (the quarter of the tithe) on the citizens of his bishopric. The document aimed at proving the episcopal lordship over the city of Poreč and fixing the tributes due to the Church of Poreč, forged in the first half of the 13^th century (before 1222).

In the name of Patriarch-margrave Berthold V of Andechs, John de Riva, the general gastald in Istria, orders a Nicholas de Roço of Poreč and all his supporters to present themselves in front of the patriarch in Friuli and to respond to allegations raised against them by a Marino de Mengoso of Poreč and his supporters.
