'This (levelling) is performed either with the dioptra, the level (*libra acquaria*) or the chorobates. The latter instrument is, however, the beste inasmuch as the dioptra and level are often found to be incorrect. The chorobates is a rod about 20 feet in length, having two legs at its extremities of equal length and dimensions, and fastened to the ends of the rod at right angles with it; between the rod the legs are cross-pieces fastened with tenons, whereon vertical lines are correctly marked, through which corresponding plumb-lines hang down from the rod. When the rod is set, these will coincide with the lines marked, and show that the instrument stands level.'—(*ibid.*, Book VIII, Chap. VI.)
