Conlocetur ad libellam marmoreum amusium mediis moenibus, aut locus ita expoliatur ad regulam et libellam, ut amusium non desideretur, supraque eius loci centrum medium conlocetur aeneus gnomon, indagator umbrae qui graece sciotheres dicitur.
Let there be placed to a level a marble dial, somewhere in the middle of the city; or let a space be so polished to rule and level that the marble dial is not wanted. Above the middle point of that place, let there be put a bronze indicator to track the shadow (which in Greek is called sciotheres).
