Caelum Constellation

Caelum Constellation

Caelum constellation is faded constellation in the southern hemisphere. Stars that form this constellation actually form a curved line and are not that bright. Neighborhood constellations are Eridanus, Columba, Pictor, and Horologium.

This constellation was first spotted by French astronomer Laccaille after he named some constellation in the southern hemisphere once the telescope was invented. They had not been recognized before and were linked to other known constellations. Caeleum is also not named by mythical creature or animal, and it signifies the graving tool that was used to engrave copper and steel. This helped in book printing. The name Caeleum has Latin origin and it is the word for the chisel.
Caeleum is a small constellation and its original name was Caela Sculptoris. 

At first, Caelum appeared in Lacaille’s map of the southern stars in 1756. Now is recognized by IAU and is bordered by the Dorado, Pictor, Horologium, Eridanus, Lepus, and Columba constellations.

Its name in Latin is translated as ‘chisel’ – a word that could also signify ‘the heavens’.
In antique times it was said that the sky (heaven or Caelum) is rounded, that is burning and spinning at the same time. The sky is referred to as ‘caelum’ because the constellations figurines looked like an engraved vessel, or ‘caelare’.
Lacaille saw this constellation as representing “les Burins”, or the tools of a sculptor.
