Supra basim eriguntur regulae dextra ac sinistra scalari forma conpactae, quibus includuntur aerei modioli, fundulis ambulatilibus ex torno subtiliter subactis habentibus fixos in medio ferreos ancones et verticulis cum vectibus coniunctos, pellibusque lanatis involutis.
On the base, uprights are set up right and left, with rungs like a ladder. Between these, bronze cylinders are enclosed. Pistons which move up and down are accurately wrought on a lathe, and with iron piston rods fixed in the middle. These rods are joined by pins to the levers, and the pistons are covered with leather and wool.
