Ruler

A ruler, sometimes called a rule or line gauge, is an instrument used in geometry, technical drawing, printing and engineering/building to measure distances and/or to rule straight lines. Strictly speaking, the ruler is essentially a straightedge used to rule lines, but typically the ruler also contains calibrated lines to measure distances.

    For in the division of the nations of the whole earth he set a ruler over every people; but Israel is the Lord’s portion: whom, being his firstborn, he nourisheth with discipline, and giving him the light of his love doth not forsake him. Therefore all their works are as the sun before him, and his eyes are continually upon their ways.
    Apocrypha. Ecclesiasticus 17:17-9.

    A scholar, in his Segmenta, left a note,

    If more unreal than New Haven, is not
    A real ruler, but rules what is unreal.”
    Wallace Stevens (1879–1955)
