The astronomer and mathematician worked as a land and sky surveyor in southern Africa and had set himself the goal of filling in the gaps between the existing constellations.

He mentions that he also defined the Southern Triangle not far away, which seems to fit the group. Lacaille also invented the compass on the centaur's front hoof to honor the profession of technical drawing.

	~~===Origin of Constellation===~~		Nicolas Louis de Lacaille explicitly wanted to name contemporary instruments to distinguish these small gap-filling constellations from the classical ones.
