Beausoleil, Jean du Chatelot, Baron de (ca.
15761643)
German mineralogist and alchemist who lived during the
first half of the seventeenth century. He traveled over most European
countries looking for metals with the aid of a divining
ring. In 1626 his instruments were seized under the pretext
that they were bewitched, and he was imprisoned in the Bastille,
where he died in 1643. In 1617 he published a work entitled
Diorisinus, id est defintis verae philisophice de materia prima
lapidis philosophalis. Beausoleil was the greatest of French metallurgists
of his time. (See also Radiesthesia)
