Columnarum striae faciendae sunt xxiiii ita excavatae, uti norma in cavo striae cum fuerit coniecta, circumacta anconibus striarum dextra ac sinistra tangat acumenque normae circum rotundationem tangendo pervagari possit.
The flutes of the columns are to be twenty four, hollowed out in such a way that if a set square is placed in the hollow of a flute and moved round its ends, it will touch the fillets on the right and left, and the point of the square will touch the curve as it moves round.
