This celebrated poem was written in the _prison de Saint-Lazare_. _La
Jeune Captive_ was a Mademoiselle de Coigny. She had, at the age of
fifteen, married the Marquis de Rosset, later on Duc de Fleury. She was
twenty-five at the time of her imprisonment. She was set free after
the 9th of Thermidor. This poem first appeared in the _Décade
philosophique_, hardly six months after the death of Chénier.
