Haec autem, quae erunt contra columnas, perterebrata sint ad canalem, qui excipit e tegulis aquam caelestem; mediana autem sint solida, uti, quae cadit vis aquae per tegulas in canalem, ne deiciatur per intercolumnia neque transeuntes perfundat, sed quae sunt contra columnas, videantur emittere vomentia ructus aquarum ex ore.
But these which will be against the columns are to be pierced for a gutter which takes the rainwater from the tiles. The intervening heads are to be solid so that the water which falls over the tiles into the gutter, may not fall down through the intercolumniations upon the passers by. But those which are against the columns are to seem to vomit and let fall streams of water from their mouths.
