Norma Constellation [Bode]

Norma et Regula, the Level and Square, originally was composed of some unformed stars of Ara and Lupus, within the branches of the Milky Way, just north of Apus; but later it became the Southern Triangle of Theodor and Bayer. According to Ideler, it was altered by La Caille to its present form, and associated with a Pair of Compasses, the constellation Circinus, next to it on the north, adjoining the fore feet of the Centaur. Modern astronomers, however, call it simply Norma, and locate it as an entirely distinct constellation to the north of and adjoining the Triangle.

It is sometimes given as Quadra Euclidis, Euclid’s Square, not Quadrant as it often is incorrectly translated.

Norma contains 64 naked-eye stars, from 4.6 to 7th magnitudes, but none seem to be named. They culminate about the 4th of July, their northern limit 15° south from the star Antares, and so are visible only in low latitudes.

La Caille’s α Normae lies within the present limits of our Scorpio. ^[1]
