On October 21, 1923, The Zeiss Mark I was taken down and shipped to the Deutsches Museum in Munich, Germany, where it was installed in a 10-meter dome, becoming the first modern planetarium.
At the time the Danish/Swedish Astronomer Elis Stromgren wrote: “Never before was an instrument created which is so instructive as this; never before one so bewitching; and never before did an instrument speak so directly to the beholder. The machine itself is precious and aristocratic… The planetarium is school, theater, and cinema in one classroom under the eternal dome of the sky.”
The word planetarium is a combination of the Late Latin planeta with the Latin suffix -arium meaning a place for. The word planet comes from the Ancient Greek: (asteres) planetai meaning wandering (stars).
While the modern planetarium with electric light projectors date only from the early twentieth century, rudimentary but highly accurate planetariums have existed since antiquity, starting notably with Archimedes.
