(By the way, I bought imps of these from brigidsblest, and they came very quickly and were in good condition and well-packed.)

This is what BPAL says:

The Muses/ Urania: The Heavenly One is the Muse of Astrology and Astronomy, and guides all those who look to the stars for knowledge. She wears a flowing cloak embroidered with her beloved stars, holds a staff and a globe, and her eyes are skyward. Her scent is that of endless, star-clad space: glittering, cool, vast. Moonflower, Moroccan jasmine, benzoin, white musk, iris, moss and a flash of ozone.

In the bottle, it's vaguely appealing and flowery. On me, it becomes more musky and heady.... possibly more subtle than Titania, but with a "deeper" tone. Nice so far.
