(the Chisel; abbrev. Cae, gen. Caeli; area 125 sq. deg.) A southern constellation that lies between Eridanus and Columba, and culminates at midnight in late November. It was named Caela Sculptoris (the Sculptor's Chisels) by the French astronomer Nicolas L de Lacaille (1713–62), who charted the southern sky in 1751–2. The shortened form was adopted by the IAU in 1922.
