Mainardus II, comes Goritiae, advocatus ecclesiae Aquileiensis (c. 1158-1231)

In the name of Patriarch Wolfger of Aquileia, Henry of Gemona swears to Marco Barozzi, the envoy of Venetian Doge Pietro Zani, to uphold the treaties concluded between the Patriarchate and Venice, namely to ensure the safety of Venetian merchants throughout the patriarch’s secular dominion, to guarantee the reimbursement to any Venetian robbed within these territories, and to promptly announce to the Venetians if the Empire is planning any hostilities directed against them.

On the behest of Wolfger, the patriarch of Aquileia, and other princes gathered at the Diet of Augsburg, King Otto IV accepts the resignation of the Margraviate of Istria from Duke Ludwig of Bavaria and donates the same Margraviate to Patriarch Wolfger and the Church of Aquileia.

Berthold V of Andechs, patriarch of Aquileia, promises to the envoys of Doge Pietro Ziani and the Commune of Venice the security of Venetians within the boundaries of his temporal dominion; assures the recompense in case a Venetian ends up being robbed within his territories; promises to inform the Venetians in case of hostilities planned against them by the Empire; and he commits himself to amend the agreement, if necessary, in accordance with the Venetian doge.

Berthold V of Andechs, patriarch of Aquileia, and Count Maynard II of Gorizia, his advocate, promise to Doge Pietro Ziani and to the Commune of Venice the safety of Venetians living and operating within the confines of the temporal dominion of the Aquileian Church; promise to reimburse any Venetian if they end up robbed in the Patriarchate; to inform the Venetians if they find out that the Empire is planning any hostilities against them; and define the competences of the vicedominus of Aquileia; Venetians are promised exemptions from customs duties throughout the secular dominion of the Aquileian patriarchs and privileged judicial status.

Settlement of dispute between the Patriarch Bertold V and Count Maynard III of Gorizia by way of the arbitrational sentence promulgated by arbiters Bernard of Strassold and Clizo of Mels. Among other things, the Gorizian is forced to relinquish everything he had usurped in Istria.

Count Maynard III of Gorizia gives Pietro Dandolo another third of the fief that his uncle and father, Maynard II and Engelbert III, had granted to the late brothers Andrea and Enrico Dandolo and their nephew Marino. The Dandolos thus concentrate two-thirds of the said fief in their hands, which includes half of the tithes in Kaštion and Pidrizago and eight tithes in Piran.
