History
The French astronomer Nicolas Louis de Lacaille occupied in the 18th century, some regions of the southern sky, which were not named by name. In contrast to the classical constellations, which are named after mythological figures, its constellations wore mostly the names of technical achievements. The original name was Caela Sculptoris ( tools of the sculptor ), thus the burin represents an engraving tool, which was formerly used for the fabrication of copper or steel engravings.
