I started reading it years ago, but lost that copy. What I remember about it:
I have tried various searches on various search platforms and online bookstores/libraries, but the title is too short to narrow down the amount of results I get.
Since it was recommended to me at the time by a scholar, I am hoping it is famous enough that someone here can recognize it.
Not sure if this is what you’re looking for but worth a shot I suppose https://www.amazon.com/Rome-Galaxy-Books-M-Rostovtzeff/dp/0195002245
