So there I was, getting ready to paint the command figures for my legion that I assembled last week, but instead, I've spent a week assembling 6 large ballistae, that I will probably never use in anger.
Front left are 2 beautifully detailed plastic models from Zvezda; to the right two heavy scorpions from BTD, and at the rear 2 whopping great onagers, also from BTD. Some of the metal models had missing parts which I've replaced with matchsticks and greenstuff. I've also mounted them all on coffee-stirrer planks, which should work for the field, or in towers.
The onagers are quite possibly later than my EIRs, but what the hell; I've added to the anachronism by placing them behind c17th gabions. I mean, the Romans could have built gabions, couldn't they? I'd imagine gabions would provide useful cover agaisnt counter-battery fire. And they are lovely little resin castings which I have been itching to use.
Looking though my bits boxes, I have at least 12 more small scorpions and 6 small onagers. I also have an old plastic 54mm Britains catapult that I intend to rebuild into a whopping great 28mm stonethrower. Clearly I will need to work up some siege rules!
