Pagano della Torre, the incumbent patriarch of Aquileia, writes to his subjects, the Commune of Dvigrad, notifying them that Nassinguerra IV of Castropola is on their way to visit them, whom they ought to help in any way they can, as long as their actions do not lead to war with Venice.
Paganus Dei et Apostolice Sedis gratia sancte sedis Aquilegensis patriarcha dilectis fidelibus nostri ..a gastaldioni, iudicibus, Consilio et Communi Duorum Castrorum gratiam nostram et omne bonum.
Cum nobilis vir, dilectus fidelis noster Nassinguerra de Castro Pole venire personaliter intendat pro quibusdam suis negotiis ad terram nostram predictam Duorum Castrorum, devotioni vestre presentium tenore mandamus, quatenus ipsum in eadem terra benigne recipiatis, et eidem in quibuscumque potestis amicabiliter serviatis, dummodo propter hoc non subeamus guerram cum Venetis, quam cum eis subire non intendimus ullo modo.

The document shows that, while the House of Castropola had possessions and jurisdictions in Dvigrad, the town itself remained under the secular potestas of the Patriarchate of Aquileia.
This war against the Venetians that the patriarch refers to regards the recent subjection of Pula to Venice (see doc. 1331_SP), an action that sparked new conflicts between the Commune of Venice and the Aquileian patriarchate.
