Urania's Mirror
An illustration by Sidney Hall for Urania's Mirror, a set of 32 astronomical star chart cards first published in November 1824. These cards, which were based on Alexander Jamieson's A Celestial Atlas, had holes punched allowing them to be held up to the light to view a realistic depiction of the constellation.

The illustrations of the constellations in Urania's Mirror are redrawings from those in Alexander Jamieson's A Celestial Atlas, published about three years earlier, and include unique attributes differing from Jamieson's sky atlas; one of these is the "Norma Nilotica" – a measuring device for the Nile floods – seen here held by Aquarius, the water bearer.Lithograph credit: Sidney Hall; restored by Adam Cuerden
