📜 Mythology

Microscopium is a modern constellation with no classical mythology. It was created by Nicolas-Louis de Lacaille during his expedition to the Cape of Good Hope (1751-1752) to honor the scientific microscope. The compound microscope, developed in the early 17th century, was transforming biology and medicine by revealing a previously invisible world of microorganisms. Like many of Lacaille's constellations, it celebrates the tools of scientific inquiry.
