Check out this Official Postcrossing card from Russia! This intriguing illustration is known as a star chart (or star map… or celestial map, sky map, sky chart… you get the idea…), and it’s what you would expect a star chart to be – a chart showing the stars in the night sky. This particular one was designed by Frederik de Wit, a Dutch cartographer (creator of maps) in the late 1600s. If you look closely (like REAL closely), you can see black dots in both of the large circles – these represent the stars! Everything else within the circles represents constellations. In western astrology, these constellations are based on Greek mythology, which is why you see some pretty unique and perhaps bizarre entities. Take, for example, Cetus in the right circle, towards the top, top-right-ish. You can’t miss it – it’s the one with the lower half of a fish and the torso of a… actually I don’t know what animal that torso belongs to, but it is vicious-looking! Fun fact: Cetus’ role in Greek mythology was a sea monster that Poseidon (the god of the sea) sent in response to Queen Cassiopeia claiming that she and her daughter, Andromeda, were more beautiful than the Nereids (sea nymphs), who often hung out with Poseidon. I would say that the vindictiveness is “off the charts” but… clearly it’s “ON the charts”. Get it… ‘cause… Cetus is on the charts here… and “off the charts” is an idiom… I’ll stop. Thank you so much for this stellar postcard, Liliya! (Get it, ‘cause… “stellar”… and stars… okay NOW I’ll stop…)
