Who knows this artist?

[v-v]

I have a few graphic works, signed M. Zakaryan. 1918.
I know little about the author. Almost nothing. : (
In the Internet found a snippet from the book "Vollar A. Listening to Cezanne, Renoir, Degas, where Degas' refers to" his friend Zakaryan "who" can work at least twenty years with one walnuts, grapes and berries with a knife, only changing their places! .. "
I would be grateful for any information on this artist.
