A faint constellation south of Cetus and Aquarius, invented by the French astronomer Nicolas Louis de Lacaille during his mapping of the southern skies in 1751–52. His original name for it, given on his planisphere of 1756, was l’Atelier du Sculpteur, the sculptor’s studio. It consisted of a carved head on a tripod table, with the artist’s mallet and two chisels on a block of marble next to it. On Lacaille’s 1763 planisphere the title was Latinized to Apparatus Sculptoris. In 1844 the English astronomer John Herschel proposed shortening it to Sculptor. Francis Baily adopted this suggestion in his British Association Catalogue of 1845, and it has been known as that ever since.

Bode in 1801 dispensed with the block of marble and moved the sculptor’s tools to the top of the table along with the carved bust, as depicted here. In place of the marble block he created the constellation Machina Electrica, but it never achieved wide currency. The stars of Sculptor are of fourth magnitude and fainter, and none are named.



Chinese associations
In Chinese astronomy, five stars in this area were seen as forming a hook shape that represented Fuzhi, a sickle used for harvesting crops. As is often the case with such far-southern Chinese constellations, the exact stars involved are difficult to identify with any certainty. Another three stars in this area formed Fuyue, an axe for executions or cutting crops, but opinions differ as to whether this constellation lay in western Sculptor or farther north in Aquarius. Similar questions concern Bakui, a constellation representing a net for catching birds or possibly the official in charge of the catch. Some authorities place Bakui in Sculptor, extending southwards into Phoenix, while others think it lay farther north in Cetus. Most likely the Chinese themselves used different stars at different times to form these constellations.
