LIBRA

(Abbreviation: LMI).

One of the Zodiacl constellations. It is however, decidedly obscure. It was originally known as Chelæ Scorpionis (The scorpion’s claws). Some Greek legends associate it, though rather vaguely, with Mochis, the inventor of weights, and measures. There are five stars above the forth magnitude.
