Trajan 3  Sugerida por marty666 

Not a font.

But here are some Greek serif fonts: https://www.myfonts.com/collections/tags/greek-fonts?page=1&refinementList%5Bfont_data.categories.lvl0%5D%5B0%5D=serif

You can try this text ΣΑΡΑΣΕΒΑΣΤΟΝΓΕΡ (3rd line of your sample)

Absolutely not the font, but i hope it helps
