Tympani autem, quod est in fastigio, altitudo sic est facienda, uti frons coronae ab extremis cymatiis tota dimetiatur in partes novem et ex eis una pars in medio cacumini tympani constituatur, dum contra epistylia columnarumque hypotrachelia ad perpendiculum respondeant. coronaeque supra aequaliter imis praeter simas sunt conlocandae. insuper coronas simae, quas Graeci ἐπαιετίδες dicunt, faciendae sunt altiores octava parte coronarum altitudinis. acroteria angularia tam alta, quantum est tympanum medium, mediana altiora octava parte quam angularia.
