AHA !....light bulb moment here. One thing, a slight anomaly, is that if Philip’s column arrived at the ridge line, wheeled 90 degrees left and thus formed line, then the Guard Peltasts at the head of the column would have ended up in the ‘wrong’ position – on the left of the right wing ( and in the centre once the left wing joined ). Their proper place, of course, was in the place of honour on the right of the line. Given “wheel” is wrong, then it becomes apparent what actually happened is that the Peltasts, heading the column and likely led in turn by their ‘Agema’ halt on the ridge-line and form the right of the line, with the following files/sub-units forming up successively beside one another to their left – thus ‘filling the line to the left’ and extending it, in exactly the normal way of deploying into line from column !! And the Guard Peltasts are then exactly where they should be, on the right...... as so often, it pays to check the EXACT translation. Many thanks, Agesilaos....“I can see there is still some confusion here,
3] ἅμα δὲ τῷ τοὺς πρώτους ἅψασθαι τῆς ὑπερβολῆς εὐθέως ἐξ ἀσπίδος παρενέβαλε καὶ προκατελάμβανε τοὺς ὑπερδεξίους:
Translates ‘As soon as [ama de] the first ones [toi tous protous] had reached [apsasthai] from the pass [tes hyperboles] they directly filled the line to the left [eutheos ex aspidos parenebale] and occupied the heights first [kai prokatelambane tous hyperdexious].
The ‘trusty Loeb’ is here completely wrong as ‘parenbalein’ does not mean ‘to wheel’ but to ‘fill the line’ literally ‘to set beside’....”
I won’t comment on the rest of the post because I think that both Paralus and I ( see our last posts) have dealt with why the mechanics of them initially deploying 8 deep in close order is almost certainly incorrect....
So now your hypothesis has Philip’s column forming 16 deep in ‘open order’, then 8 deep in ‘close order’ ( being pedantic, to call this ‘normal’ is incorrect), then opening out again to 16 deep in ‘open order’, then closing up to the right to end up 16 deep in close order, then closing up again into 'synaspismos' ( though perhaps you may not insist on the last part) ? Bit complex not to mention time-consuming with the Romans already charging up the slope. Think I prefer the simplicity of my suggested drill move.....“Philip arrived with his units sixteen deep in marching order and then halved their depth to eight in normal order viz....”
The first part of that statement is incorrect for the reasons I referred to in my last post ( and many other pieces of evidence). Poylybius [XII.19], quoting and paraphrasing Kallisthenes has Alexander’s phalanx at Issus open out as the column debouches from the pass onto the plain, and the phalanx finally closes up to ‘fighting formation’ 8 deep ; "....finally as he approached the enemy to eight deep.” – significantly the only time we are told the depth at which they fought. Significantly too, neither Polybius nor apparently Kallisthenes comment on the fact – it is not suggested that the phalanx was stretched exceptionally thin to cover the ground, which would therefore appear to be perfectly normal for ‘pyknosis’. Assuming that it was thinned to cover the ground is an unwarranted assumption, based on the incorrect assumption that ‘close order/pyknosis’ was 16 deep !“Polybios describes the phalanx as fighting sixteen deep because that was its normal depth; consider the hybrid phalanx described by Aristoboulos, that can only fight sixteen deep, or Issos where Alexander had to move to eight deep to cover the ground.”
In fact this very passage is one of many that supports the view I expounded earlier vis-a-vis it being ‘open order’ that was 16 deep, for Polybius specifically says that “ ..a stade [200 yards aprox, depending on whose stade] when the men are 16 deep will hold sixteen hundred, each man being at a distance of six feet from the next..” ( i.e. 16 deep is in normal/open order)
Polybius also explains why a phalanx needs to advance in ‘open’ order in this passage too.
Incidently, Polybius’ criticisms of Kallishenes are somewhat flawed....
