Source
The original is lost; the document survives in two later manuscript traditions:
D = Venice, Biblioteca Marciana, ms. lat. Zanetti 400 (= 2028), fol. 58v; 14th-century copy, inserted in Andrea Dandolo’s Chronicle of Venice (the so-called Chronica per extensum descripta of which this is the codex optimus).
T = Venice, Archivio di Stato di Venezia, Pacta e aggregati, Codex Trevisanues, fol. 22r; late 15th-/early 16th-century simple copy based on a copy from the nowadays lost Codex Egnatii, presumably from the 14th century, under the following title: Epistola preceptionis directa Calisto patriarchę Aquilegensi a Gregorio tertio.

Gregorius episcopus, servus servorum Dei, Calixtoa et cetera.b

Iam triennium evolutum, decessoris nostri temporec plurimis fuerat suplicationibusd constitutum, dilectionem tuam ab hac summa atque apostolica Dei Ecclesia pallii promeruisse benedictionem commonit ut equoquee, ut in sanctę nostrę ecclesięf scrineis testantur volumina, fuisse, ne umquam audensg tu vel tui futuri successores aliena invadere iura aut temeritate qualibet illicita penetrareh, sed ut humiliter utilisi tibi concessum pallium fueras institutus merito magis est oneris quam honoris.

Nunc vero cognovimus, contra canonum instituta cuiusdam protervię ausoj temeratorem te extitisse, et valde audita doluimus. Cognovimus enimk, quosl ita habetur nullus fieri serrem murmuratione, quian aviditate devictus ausu illicitoo pervaserisp possessiones, que Centenaria et Mussiones nuncupantur, pertinentes monasterio sanctę Dei genitricis sito in insula Barbiana, quod prisco et longo tempore sancta iure possidet Gradensis ecclesia et eius hactenusq fuerat ditionisr.

Quod quia aliena nulli licet invadere, precipue sacerdotibus, quia contra Deum est, precipimus beati Petri [apostolorum]s principis auctoritate, cui a domino Deot et salvatore nostro ligandi atque solvendi in cęlo terraque potestas concessa est, ut ea, quę pervadere contra legem ausus esu, in presenti cum omnibus ei pertinentibusv in integro restituere Gradensi archiepiscopow debeas, cuius ditionix pertinere videtury, et ab insolenti[a]z recede[re]a'. Non enim sinimus, scias, licitare tibi illicita et aliena brachio possidere; potius molestia sacerdotali constrictus tuis te habetob' et, ut fortic' servans, pervasa restitue.

Scias enim, si extiteris temerator et reddere distulerisd' aliena, apostolica sententia canonicae' te subiacere correctioni atque penitentięf', dum iusta fueris condemnatusg' sententia.

Editor's Notes

The papal warning issued to Callistus is one of the earliest evidence of territorial disputes between the two patriarchs, of Grado and of Aquileia. The occupied possessions – Centenara and Musione – are located right between Grado and Aquileia.

Patriarch Callistus remains notable for his eventful relations with the Lombard king Liutprand and his duke Pemmo, who at one point even imprisoned the prelate. Callistus is also known for his magnificent ciborium over a baptistry in Cividale (see the picture below), one that served as a model for the ciborium in Novigrad in Istria, erected by Bishop Maurice (see doc. 776_HPC).
