Antoine Lavoisier

Not one of his ten planets sits in a fire sign. Earth takes five, water three and air two. The chemist who named oxygen has no fire in his chart, which is a pun on two unrelated senses of the word element and is worth stating only so that nobody mistakes it for a finding. The record says Lavoisier named oxygen, disproved phlogiston and established that matter is conserved, and that he was guillotined during the Terror, the judge said to have remarked that the Republic had no need of scientists.

The Sun, Mercury, Jupiter and Saturn fill nineteen degrees of Virgo, the sign built on doing something properly and being useful, with Mercury on the first half degree of it. Four planets in the sign of exactness, in the man the record credits with establishing that matter is conserved, is the fit a reader will want and the one this chart actually supports. His Moon sits at twenty seven degrees of Scorpio at noon and may have crossed into Sagittarius, so it is left out.

The Sun sits a fifth of the way round from Pluto at two thirds of a degree, which is power that is usable rather than overwhelming: resilience, and an instinct for what is really going on beneath a situation. Mars sits square Uranus at nine tenths, action without warning, and Saturn sits in hard contact with that same Uranus at just under half a degree, order against revolt. A reader who knows how this chemist died will reach for those last two. They are the meanings of two angles in any chart, and an execution is a decision that other people made.

He died in Paris on 8 May 1794, at fifty. Uranus stood sixty degrees from his natal Mars at just over a fifth of a degree that day, Neptune at that same angle to his natal Sun at under a third, and Pluto square his natal Moon at four tenths, with Jupiter in easy contact with the Sun at the same orb. The Moon was at its first quarter and sixty five per cent lit, which is the phase that acts decisively and often has to break something to do it.
