A circle with a vertical stroke rising to a cross — Uranus.
Also known as: Herschel symbol, H with a circle symbol
Uranus was discovered in 1781, long after the classical planets, so its symbol was invented rather than inherited. Two competing forms resulted, and both remain in use — a rare case where the origin of a symbol is documented precisely.
Denotes the planet Uranus in astronomical notation.
Contexts: History
Is held in modern astrological tradition to signify disruption and sudden change; it has no classical astrological meaning, the planet being unknown before 1781.
Recorded as what astrological tradition assigns, not as a finding. Symbolwise does not assert that any planet influences anything, and astrology has no empirical standing.
Contexts: History
Has two competing forms because the planet was discovered in 1781 and its symbol had to be devised: one is a monogram of Herschel's initial, the other a circle with a spear-like stroke in the older planetary style. Both are current.
Unusually for this batch, the origin is a matter of record rather than reconstruction — the symbol was designed within documented history.
1781 onward · Contexts: History
A circle with a vertical stroke rising from its top, crossed near the upper end by a short horizontal bar.
Both were discovered after the classical era — 1781 and 1846 — so both had symbols devised for them rather than inherited, and neither has an alchemical meaning.
