An attempt to examine North-western part and boundary lines
Armen H. Gharagyozyan
Owing to the observations of the Armenian plateau’s ethno-geographic environment, it is confirmed that Achaemenid Empire’s XVIII satrapy was formed with Tchorokh basin from the beginning of the VI century. The etymology of ethnic names of the tribes inhabiting that territory indicates their Indo-European – Armenian descent. Though, in the first half of the II century it was obvious that Tchorokh basin was populated by Armenians.
As a result of Armenian plateau’s ethno-geographic observation it was discovered that the provisional name of the lake Van was Aghi tsov, which meaned the Sea of Sun or God Sun’s sea. The same meaning is conspicuous also in the name Aghtamar and is derived from the provisional version Alde of mythological name Halde.
The lake Urmia was perceived through its color characteristics as blue, clear sky or heavenly plait, celestial gift and vivifying song, as well as the name Sevan of the lake-name Geghama tsov.
