did you guys know that Horologium means CLOCK?

here is why the constilation was given it's name:

"Horologium was named by Abbé Nicolas Louis de Lacaille. It was originally named Horologium Oscillitorium to honor Christian Huygens, the inventor of the pendulum clock in 1656-57. Like many of de Lacaille's other cumbersome constellation names, Horologium Oscillitorium was shortened in modern times. Huygens is also famous for discovering Saturn's rings."

Abbé Nicolas Louis de Lacaille also named these constilations:
