Sin autem ionicae columnae fient, scapus praeter spiram et capitulum in octo et dimidiam partem dividatur, et ex his una crassitudini columnae detur; <spira> cum plintho dimidia crassitudine constituatur; capituli ratio ita fiat, uti in libro tertio est demonstratum.
But if the columns are Ionic, the shaft apart from the base and capital is to be divided into 8 parts and of these one is to be given to the diameter of the column. The base, with the plinth, is to be of half the diameter. The capital is to be designed as set forth in the third book.
