Writers need tactics. Tactics is the only known surviving work of philosopher Asclepiodiotus (c. 1 BCE – unknown). The text focuses on the titles and formation needed in the phalanx, including the use of chariots and elephants. Chapter V details the character and appropriate size of arms including the use of bronze shields and spears of varying lengths.
“And the Macedonians, men say, with this line of spears do not merely terrify the enemy by their appearance, but also embolden every file-leader, protected as he is by the strength of five…”
καὶ Μακεδόνες μὲν οὕτω τῷ στοίχῳ, φασί, τῶν δοράτων οὐ μόνον τῇ ὄψει τοὺς πολεμίους ἐκπλήττουσιν, ἀλλὰ καὶ τῶν λοχαγῶν ἕκαστον παραθαρσύνουσι πέντε δυνάμεσι πεφρουρημένον
The things you fear in your writing, the things you are afraid to write are also the things that give you courage. Your greatest enemy, writer, may be you. Embolden yourself.
