History
This constellation was named by Nicolas Louis de Lacaille during his stay at the Cape of Good Hope from 1751 to 1752. He originally called it Norma et Regula (the Normal (a Set Square) and the Ruler (a Level) ), referring to the carpenter's tools. The constellation had previously been called the Southern Triangle (no relation to Triangulum Australe) and Quadrans Euclidis (Euclid's square). Since it lies in the south, and was created in the 17th century, this constellation has no early or classical mythology associated with it.
