Sin autem colossicotera amplitudinibus et ponderibus onera in operibus fuerint, non erit suculae committendum, sed quemadmodum sucula chelonis retinetur, ita axis includatur habens in medium tympanum amplum, quod nonnulli rotam appellant, Graeci autem amphieren, alii perithecium vocant.
If, however, the works involve loads of immense dimensions and weight, we must not trust to the windlass. But an axle held in sockets like the windlass is to be inserted having in the middle a large drum, which some call a wheel: the Greeks amphieres, or otherwise perithecium.
