I read a book on the tenth legion as a teenager (15-20 years ago) and a statement in it about Roman soldiers pay has always stuck with me. The book stated that a soldiers salary banding never increased over 100+ years. Due to the fact that the costs of goods never really rose from one year to the next. The example the book used was that if a harvest was reasonable, a loaf of bread cost the same one day as it did a generation later.

Was this true?? If it was why, what was different about the Roman economy to mean inflation wasn’t really a thing??
