MOD'ULUS. In a general sense, a measure by which any thing is measured; but more specially, a module, or measure of division, adopted by architects as a standard by which the proportions of an order, or the entire building, may be regulated. It may be taken at pleasure; but the diameter or semidiameter of a column at the bottom of the shaft is the module mostly resorted to. Vitruv. v. 9. 3.

2. In aqueducts, a water-meter; same as CALIX, 3. Front. Aq. 34. 36.
