Use of the hoplon into the Roman period?

[Idomeneas]

actually by the word ΟΠΛΟ we mean ''weapon''. It just happens that today weapon generally is firearm. The normal term is ΠΥΡΟΒΟΛΟ ΟΠΛΟ. weapon that projects fire. There are many terms survived or that took close meanning. For example ΠΟΡΠΑΞ of shield became ΠΟΡΠΗ the belt buckle. ΤΕΛΑΜΟΝ is still used not for the sword/shield strap but for the one of the firearm. ΚΡΑΝΟΣ emains the same while bayonet is called ΞΙΦΟΛΟΓΧΗ meanning swordspear
