(Claude), an eminent Latin poet of the 17th century, was born at Chinon, in Touraine, and practised physic there with reputation; but having declared against the pretended possession of the nuns of Loudun, in a manuscript treatise, the original of which was deposited in the library of the Sorbonne, he was obliged to retire into Italy, where he became secretary to the marshal d'Elftrees, the French ambassador at Rome. In 1655 Quillet having published in Holland a Latin poem, entitled Callipedia, under the name of Gallicius Letus, he there inserted some verses against the cardinal Mazarin and his family; but that cardinal making him some gentle reproaches, he retrenched what related to the cardinal in another edition, and dedicated it to him, Mazarin having, before it was printed, given him an abbey. He died in 1661, aged 59, after having given Menage all his writings, and 500 crowns to pay the expense of printing them; but the abbe took the money and papers, and published none of them. His Callipedia, or the art of getting beautiful children, has been translated into English verse.
