Hi There:
I'm an author writing a book set in and around First Century Syria (Province). My research led me to the Cursus Publicus, which was the courier service of the Empire. At daily intervals they had mansiones, staying places. Everything I find says that these were reserved for official use...although abuses did exist. "Normal" travelers had to find accomodations in private inns, cauponea, or the wealthy could stay at a tabernea.
The one thing I have been unable to find out is whether the official traveler had to pay for accomodations in the mansiones. It seems not, since they were on official business. Then again, maybe they got a room but had to buy their own food.
I'm trying to be as historically accurate as possible. If anyone has any insights, I'd appreciate them. If you want to make an educated guess, that'd be OK too. Right now all I have is an uneducated guess. (Me.)
Thanks.
