Hall of the Muses
This Hall, opened to the public in 1784, was intended for the display of a series of sculptures which had been found in the so-called Villa of Cassius near Tivoli, and which included many statues of the Muses, an Apollo as holding the lyre, an Athena, herms and portraits of famous Greek men, all dating from the time of the Emperor Hadrian.
The statues were greatly modified by 18th century restorers: some of them did not originally depict muses and were modified in order to complete the full number of nine personifications of the arts. The frescoes by Tommaso Conca on the vaulted ceiling represent Apollo and the Muses as the inspirers of the arts. In the 1800s the Pompeian red paint was used to cover landscapes which had previously provided backgrounds for the various statues.

https://en.wikipedia.org/wiki/Urania

Urania; Ancient Greek: Οὐρανία, romanized: Ouranía; modern Greek shortened name Ράνια Ránia; meaning "heavenly" or "of heaven") was, in Greek mythology, the muse of astronomy. Urania is the goddess of astronomy and stars, her attributes being the globe and compass.
The muse Urania is sometimes confounded with Aphrodite Urania ("heavenly Aphrodite") because of their similar name.

Urania was the daughter of Zeus by Mnemosyne and also a great-granddaughter of Uranus. Some accounts list her as the mother of the musician Linus by Apollo or Hermes or Amphimarus, son of Poseidon. Hymenaeus is also said to have been a son of Urania.
