Psalterium Georgii can be seen on the left of this card from Urania's Mirror (1825), next to Cetus.
Psalterium Georgii (also Harpa Georgii) (Latin for George's harp) was a constellation created by Maximilian Hell in 1789 to honor George III of Great Britain. It was created from northern stars in Eridanus and was next to the constellation Taurus, and included 10 Tauri. It is no longer in use.
