Answer:
I think it is Philosophers
Step-by-step explanation:
Credit Alexander was from Macedon, but I think Aristotle was from Greece. I read a whole book about Alexander the Great and he was taught by Aristotle who was a philosopher the book said that Aristotle taught Alexander everything like math, science, politics and the arts.
I am sure a artisan is like a craftsman and a warrior would not be a teacher in Greek society unless teaching training soldiers in a barracks. Then politicians I think would have no time to teach pupils but if I would chose something other than philosopher it would be politician.
