Seal of Planets –
From the top left descending: The Sun, the Moon, nestled in the “Horns” of Mercury is the Star, which then becomes Venus (note the inverted Seal of Sulphur), then Saturn.
On the right, descending: Earth, which touches Mars – and Uranus – which sit on the bough of Jupiter, to the left is Pluto and its moon, Charon, all of which rest on the inverted Trident of Neptune.
As far as uses go, best for works involving: Cosmic Oneness, Completion, Unity, Balance, Collective Archetypes and Community. Also, micro-cosmically for things involving the faceted psyche, consciousness or soul.
