Plumbline
The plumbline is a Outil consisted of a ballasted wire used to obtain verticals (or at least direction of the Pesanteur at a precise place).
It is used for example to assemble vertical walls in Maçonnerie.
It is also used in Dessin and Peinture in order to determine the presence of points of alignments for example at the time of the recopy of a plaster, the human eye tending to easily let itself mislead by certain forms.
Handling
The Sphère in Laiton is Lest ée of Plomb. It is also suspended on the string via a “stopper” bored and threaded out of brass. If this string is unreeled, it slides through a hold out of wooden thickness identical to the ray of the sphere. On all the height of a vertical masonry, the equator of the sphere must come very close to work.
Symbolic system
The vertical Symbolique of the wire with Plomb suggests inter alia rise, the perfection of oneself, the effort, or the deepening.
