<jats:p>Some recent statements in the scholarly literature exaggerate the length of ancient catapults, so a critique is offered, and an explanation for the source of the error is suggested. A brief account is given of how to calculate the dimensions of the ‘classic’ types of ancient catapult according to the formulae for their construction in Philon and Vitruvius. The implications for fitting artillery to fortifications are highlighted. It is emphasised that the type of device for which first generation artillery towers were designed were tension-powered catapults, not torsion-powered models. They were bow catapults (tension), not spring catapults (torsion), and therefore, since the formulae apply only to spring catapults, none of the ancient formulae apply to the machines for which first generation artillery towers were built.</jats:p>
