Horologium

Horologium (pronounced /ˌhɒroʊˈlɒdʒiəm/ or /ˌhɒrəˈloʊdʒiəm/; genitive Horologii /ˌhɒrəˈlɒdʒiaɪ/) is a small and faint constellation in the southern sky (declination around −60 degrees). Its name is Latin for clock. It was created in the eighteenth century by Abbé Nicolas Louis de Lacaille, who originally named it Horologium Oscillitorium after the pendulum clock to honour its inventor, Christiaan Huygens. The name has since been shortened to be less cumbersome.
