Beauchateau, François Matthieu Chatelet De

, born at Paris in 1645, was the son of a player, and was considered as a poet when no more than eight years old. The queen, mother of Louis XIV. cardinal Mazarin, the chancellor Seguier, and the first personages of the court, took pleasure in conversing with this child, and in exercising his talents. He was only twelve years old when he published a collection of his poetical pieces, in 4to, under the title of “La Lyre de jeune Apollon,” or, “La Muse naissant du petit de Beauchateau,” with copper-plate portraits of the persons he celebrates. About two years afterwards he went over to England with an ecclesiastic. Cromwell and the most considerable persons of the then government admired the young poet. It is thought that he travelled afterwards into Persia, where perhaps he died, as no farther tidings were ever heard of him. He had a brother, Hypolite Chastelet de Beauchateau, an impostor, who pretended to abjure the Roman Catholic religion, and came over to England under the disguised name of Lusancy. Moreri and Anth. Wood in Ath. Ox. vol. II. give an account of this adventurer.2
