History. This constellation was added by de Lacaille in 1752 A.D., under the name Machine Pneumatica.

Influence. It is said to bestow prosperity, harmony and spiritual force. ^[1]

Antlia Pneumatica, the Air Pump, is La Caille’s Machine Pneumatique, at first Latinized as Machina Pneumatica; but astronomers know it as simple Antlia.​

The constellation lies just south of Crater and Hydra, bordering on the Vela of Argo along the branches of the Milky Way; Gould assigning to it eighty-five naked-eye stars.

He thinks that α, the red lucida, may be a variable, as his observers had variously noted it as of from the 4th to the 5th magnitude, and Argelander entered both of these.

La Caille’s β lies within the present limits of Hydra. ^[2]
