Name used since Renaissance times (from the Latin regula).
Description
Instrument for drawing straight lines. Usually made of wood, but sometimes of ivory or brass, rulers generally had a squared edge for tracing lines in dry point or pen-and-ink, and a rounded edge for tracing lines by pencil and transcribing measurements. In his treatise on architecture Vincenzo Scamozzi describes it as follows: “…rulers should be made of pear wood, or apple wood, or jujube or sorb, either domestic or wild … [they have] a squared edge for drawing occult lines, or blunt with the point of an ivory stylus, or with a pencil point … Rulers or vanes… [can be] of ebony, or ivory … and those made of metal leave stains on the paper …”
