Cold Case Spoiler
Well, this explains Cold Case.
Now you've done it.
Also: Textbooks on languages.
Also, also: Kamasutra.
Also, also, also: Ivy has to be able to understand all languages, since she's the repository of _human_ knowledge. All of humanity. Not just the English speaking population.
Case and point:
"I know everything about you, Lartessa," Ivy said, her tone flat, passionless. "It was all recorded, of course. Everything was, in Thessaloniki in those days. Your father's failing business. Your sale to the temple of Isis. If you like, I could draw you a cost-benefit analysis of your training versus your earnings in your first year at the temple, before Nicodemus came. I could use charts to make it easier for you to understand. And color them in with crayons. I enjoy crayons."
Thessaloniki is in Greece. While they do speak some English there nowadays, they most definitely didn't do so 2000 years ago. And I'm quite certain that they didn't write their documents in English.
Bonus points for temple of Isis/Inana/Ishtar. There was a yearly tradition: Prostitution for charity. Every female member of the church if Ishtar had to undergo this _once_ in her life and be a prostitute for whatever money got offered. This money would go to charity then. If they didn't get picked, they had to participate again and again, until they got picked.
