I don’t know what story the poster was referring to, but the use of Roman numerals for centuries is the standard in Spanish and I assume in Portuguese too. If the poster is Brazilian, then his use of Roman numerals is of no surprise.

Exactly, in Brazil is the norm. I didn't think it could not be in english. My only while writing was if it should be "XIX century" or "century XIX". Apparently, neither :)
