Si non erit ampla magnitudine theatrum, media altitudinis transversa regio designetur et in ea tredecim cellae duodecim aequalibus intervallis distantes confornicentur, uti ea echea quae supra scripta sunt, ad neten hyperbolaeon sonantia in cellis quae sunt in cornibus extremis, utraque parte prima conlocentur, secunda ab extremis diatessaron ad neten diezeugmenon, tertia diatessaron ad paramesen, quarta ad neten synhemmenon, quinta diatessaron ad mesen, sexta diatessaron ad hypaten meson, in medio unum diatessaron ad hypaten hypaton.
If the theatre is not of large dimensions, in the middle of the height, a transverse line is to be drawn. In that, thirteen cavities separated by twelve equal distances are to be arched over, so that those vases above referred to, giving the note of the n't hyperbolaen, may be placed at each end; second from the end, vases of the n't diezeugmenn at an interval of one fourth from the last; third from the end at the parames (another fourth); the fourth set of vases at the n't synhemmenn; the fifth at the mes (interval of a fourth); the sixth set at the hypat mesn (interval of a fourth); in the middle one vase at the hypat hypatn.
