4The number of steps in front should always be odd, since, in that case, the right foot, which begins the ascent, will be that which first alights on the landing of the temple. The thickness of the steps should not, I think, be more than ten inches, nor less than nine, which will give an easy ascent. The treads not less than one foot and a half, nor more than two feet; and if the steps are to go all round the temple, they are to be formed in the same manner.
4The steps in front must be arranged so that there shall always be an odd number of them; for thus the right foot, with which one mounts the first step, will also be the first to reach the level of the temple itself. The rise of such steps should, I think, be limited to not more than ten nor less than nine inches; for then the ascent will not be difficult. The treads of the steps ought to be made not less than a foot and a half, and not more than two feet deep. If there are to be steps running all round the temple, they should be built of the same size.
