Johann Elert Bode
Francis Baily shortened this name to "Caelum", as suggested by John Herschel. In Lacaille's original chart, it was shown as a pair of engraver's tools: a standard burin and more specific shape-forming échoppe tied by a ribbon, but came to be ascribed a simple chisel. Johann Elert Bode stated the name as plural with a singular possessor, "Caela Scalptoris" – in German ("die" ) "Grabstichel" (“"the Engraver’s Chisels"”) – but this did not stick.
