 It is usually believed that the name of the Armenian king is not mentioned in the Cyropedia. Indeed, if You read the English translations available on-line You will find phrases like "Armenian king" or "king of Armenians". But not any name. This is odd, because the names of his sons are mentioned: Tigranes and Sabaris. Known as Tigran and Shavarsh in Armenian. Why would the name of the king himself miss?

Sargis Petrosyan has a theory on this matter. He thinks that the name of the king is present there and it is Armenios. The name being too similar to the ethnonym has resulted in a confused translation. According to him Armenios correspond to Other Haykak, which would be the grandfather of Tigran in Khorenatsi list. The one that was contemporary to Cyrus. Haykak is the diminutive of Hayk and if someone translates this name then it will get something like Armenios.

I have found the book in Greek. Unfortunately, my Greek is not sufficient to understand whether the term Armenios in that text a personal name or some kind adjective is.

There are other forms in the text. Like Armenoi, Armenie, Armenion. The first one is a plural the two others might be adjectives.
