Itaque Diades scriptis suis ostendit se invenisse turres ambulatorias, quas etiam dissolutas in exercitu circumferre solebat, praeterea terebram et ascendentem machinam, qua ad murum plano pede transitus esse posset, etiam corvum demolitorem, quem nonnulli gruem appellant.
Diades, then, in his books shows that he invented Movable Towers, the parts of which he used to assemble and carry round with the army; in addition to this, the Borer and the Climbing Machine by which a passage from the level up the wall was possible; further, the Grappling-hook for demolition which some call the Crane.
