On September 13, 1768, a single stone of 3500 grams fell from the sky near the town of Lucé (today called Le Grand Lucé). The meteorite was acquired by the Abbé Bachelay, priest and scientist, who sent it on to the Royal Academy of Science in Paris. The scientists there described the stone as having « a thin black crust partially covering an interior of gray cindery material scattered with an infinite number of shiny metallic grains of pale yellowish color.”
Lavoisier did for the first time in history the analysis of a meteorite, and that meteorite was Lucé. He found 55.5% vitrifiable earth, 36% iron, and 8.5% sulfur and concluded that stone was a pyrite-rich sandstone. He didn’t realize that the stone fell from the sky but he said it was a terrestrial stone struck by lightening.
When studying the catalogs of the Museums and renowned collections, total mass today is about 154 grams, which is only 4% of the initial mass !
