the zone was composed of three marches: the Syrian, later contained in the Roman province of Fourth Armenia; the Arabian, corresponding to the provinces of Arzanene or Aghdznik, Gordyene or Korche'k', and Moxoene or Mokk'; and the Median, chiefly the provinces of Persarmenia or Parskahayk' and Adiabene or New Siracene (Nor-Shirakan). The northern semicircle was formed by, in the middle, the Iberian March, based on the province of Gogarene or Gugark', and by a number of outlying principalities south-west and south-east of it. The south-eastern group was comprised of the provinces of Otene or Uti, Arts'akh, Caspiane or P'aytakaran, and, between the last two and west of them, Siunia or Siunik'; the south-western group contained the provinces of Tayk' and of Upper Armenia. The central region was composed of the northern cantons or lands forming together the province of Ayrarat, where the domains of the Arsacid royal house were situated, and the southern territories grouped--subsequently--into two provinces, Turuberan in the west and Vaspurakan in the east. The majority of the princely States were coterminous with cantons; a few of them, however included entire provinces (227).
15. All the known princely houses of Armenia, and of Caucasia, will be examined in the next Study. Here, a few historically important Armenian dynasties may be singled out; before this, however, a word needs to be said about the princely nomenclature. The earliest Armenian literary sources reveal the existence of a fully developed onomastic system involving the praenomen and the nomen gentilicium. The princely family names were by origin either territorial or patronymic, though actually the distinction between these two kinds of names was often blurred, owing to the fact that many of the princedoms seem to have derived their names from the patronymics of their ruling houses (228). Most Armenian names of countries and regions being plural in form--a relic of the tribes and clans of the past to which these territorial units owed their individuality--the word designating a principality was often the same as the plural of the dynastic surname derived from it or from which it was derived. Some dynasties, moreover, had special family titles, peculiarly their own, and others were enfeoffed of great Crown offices, and as a result some patronymics were derived from such titles and offices.
