Hevelius’s depiction of Sextans


Sextans was shown by Johannes Hevelius in his Firmamentum Sobiescianum star atlas under the name Sextans Uraniae, Urania being the Greek Muse of astronomy. Although an innovator in some ways, Hevelius was a traditionalist in others and showed the constellations in mirror-image form, as though seen on the surface of a celestial globe. Hence the constellations in his atlas appear flipped left to right by comparison with their true appearance in the sky
