, a bachelor of the Sorbonne, was
born 1603 at Paris, son of a hatter. He had neither the
taste, learning, nor merit, of M de Girac, but was not
ignorant, as that writer accuses him of being, in his dispute upon Voiture. M. du Rueil, bishop of Bayonne, and
afterwards of Angers, wished to have Costar always about
him as a literary man, and gave him many benefices. He
was eagerly received at the Hotel de Rambouillet, and in
the best companies, notwithstanding his affected airs’; for
which reason it was said, “He was the most beauish pedant, and most pedantic beau, that ever was known.
” He
died May 13, 1660. Besides his works in defence of Voiture, against M. de Girac, there is a collection of his Letters in 2 vols. 4to, containing much literary anecdote and
criticism, the latter rather in a frivolous taste, which is
likewise visible in some other of his pieces.
