I'm intrigued by ancient technologies used in weapons making from a technical point of view.
Forget personal weapons for a moment, I'm thinking of battering rams, siege towers and the like.
For me, they define the ultimate use of these technologies. I know some armies had portable siege equipment (the Augustan Roman legions and Philip of Macedon's army for example), but this consisted mainly of artillery that was transported in component form.
Consider this machine as an engineering project however -
I wonder how Demetrios' engineers expected it to move easily towards the walls of Rhodes, considering the weight of the tower and the terrain it was going to cross? Or was it a psychological weapon, built to terrify the Rhodians?
I will also mention Archimedes' engines used against the Romans, which were used in the defence of Syracuse. A machine that pulled ships from the water...? I don't imagine there was a prototype, or a development of an existing machine.
Lastly, Assyrian reliefs show siege weaponry that was still recognizable in the 15th century AD - were they the first army to use them?
I welcome your comments.
