Modulus

Mod"ule\, n. [F., fr. L. modulus a small measure, dim. of modus. See Mode, and cf. Model, Modulus, Mold a matrix.]

1. A model or measure.

2. (Arch.) The size of some one part, as the diameter of semi-diameter of the base of a shaft, taken as a unit of measure by which the proportions of the other parts of the composition are regulated. Generally, for columns, the semi-diameter is taken, and divided into a certain number of parts, called minutes (see Minute), though often the diameter is taken, and any dimension is said to be so many modules and minutes in height, breadth, or projection.
