Searching for Agrippine and another Lune Cyrano and his manuscripts

This article is a follow-up to an investigation that began five years ago concerning a manuscript collection, now held in a private archive and currently untraceable, containing rare copies of two works by Cyrano: a version of États et empires de la Lune and, above all, an early version of La Mort d’Agrippine, supposedly more virulent than the printed work; there are no other known manuscripts of the play.
