Helevius map of the heavens

at Helevius Square, near old town, Gdansk

“Hocce Hemisphaerium Firmamenti Sobiescrium Boreale” = Star chart of the Northern Hemisphere.

Helevius Square was named after Johannes Hevelius (1611-1687). He was a beer brewer in Danzig/Gdansk. He was also interested in astronomy and built a telescope on the roof of his house. His contributions to the study of the constellations are many including the descriptions of ten new ones. Ursa Major and Ursa Minor are depicted above – that’s the big and little dipper. So are Cassiopeia, Aquarius, Cancer (Cancri), and Andromeda. Some of the others you might find are Hercules, Draco, Serpenterius, Cerebrus, and Camelopardalus. Three of the constellations described by Helevius are no longer in use!
