I'm guessing here but I suspect that you had to be fairly rich to afford such a fancy bit of kit back in 200AD. Pulling that out in an encampment in the day people would stand up and take notice. Lots of uber traveler camp cred. A real status symbol. It might be like pulling out something like a light saber today.
Thanks for posting this.
