Vol. 5: A 1300 usque ad 1421
9th of May, 1367

Patriarch Marquard of Randeck invests Domnius of Rijeka, a vassal of the Church of Aquileia, with two villages in the Margraviate of Istria: Jasenovik by Kožljak and Letaj, situated between Kožljak and Vranja, under the condition that he restitutes the said villages to the patriarch’s successors upon their potential request.

The original charter is lost, and the contents are known only through a regestum in Thesauri claritas made by John, the son of Odoric Susanna, in the final decade of the 14th century; the original codex of Thesauri claritas is lost and only later copies survive of which two early fifteenth-century exemplars are considered the best:

Editor's Notes

Little is known regarding this Domnius of Rijeka other than the fact that he served both the lords of Duino and the patriarchs of Aquileia.

The toponyms mentioned in the regestum pose some problems: Coseglach and Iasinimbich / Iascimbich / Iasenubich are easily identified as Kožljak and Jasenovik; Latay / Latoy / Lathaii is without doubt Letaj to the north of Jasenovik. Bray is problematic: for Camillo de Franceschi it is Belaj in the near vicinity and to the north of Letaj; Peter Štih, on the other hand, prefers the reading Bran as featured in the later Monumenta Patrie Foriiulii and connects it with Vranja, also to the north of Letaj.

Based on this regestum and the accompanying note on the margin, Mladen Ančić (“Gradu kmeti or iobagiones castri as an Element of the Social Structure of Croatian Kingdom,” Miscellanea Hadriatica et Mediterranea 6 (2019): p. 69 fn. 88) argued that in the Late Middle Ages the concept of Istria as a region could be extended so far to the east to include Rijeka in its semantical confines. The editor finds this argument invalid as the part “in Istria” in the marginal note does not refer to Rijeka but to the possessions bestowed upon Domnius, the villages that are located in the Margraviate of Istria, both of them to the west of the Učka mountain range. The microregion between the Učka and the river Rječina was called Meran(ia), Croatia, Liburnia but never Istria, at least not in the Middle Ages – see more on that here.
