Zephyrus
Tyrants and Slaves
Only "stupid" thing I see in it is that he had to have someone translate words into something that I'm assuming he can't read.
As for the phrase, what were his reasons?
It confused me, too. Perhaps if he wanted me to do it in Greek, since that's what I'm teaching him. Perhaps he's Catholic.
I didn't ask for his reasons. It's the professional thing to do not to discuss religious preferences with students unless they ask.
