The same dial-plates ^[Note] cannot be used in all places, the shadow of the sun being sensibly different at distances of 300, or at most of 500 stadia ^[Note]. Hence the shadow of the dial-pin, which is termed the gnomon, at noon and at the summer solstice, in Egypt, is a little more than half the length of the gnomon itself At the city of Rome it is only 1/9 less than the gnomon, at Ancona not more than 1/35 less, while in the part of Italy which is called Venetia, at the same hour, the shadow is equal to the length of the gnomon ^[Note].
