Polybios says that the centurio prior led the right side of the maniple, while the centurio posterior the left one.

I don’t remember Polybius stating the centurion prior and the centurion posterior. Isn’t it the senior centurion and the junior centurion? And what evidence is there for a prior and posterior century for this period when facing the Macedonian phalanx?

I checked out the quote: Polybious use the term "the first elected" (pròtos airetheis). Anyway wath I meant is that centurions led a portion of maniple, not a single century.
