This is a ca. 1685 copy of the three-act libretto of "La Geneviefa" by Girolamo Gigli. The work was dedicated to Prince Francesco Maria of Toscana. The Sienese composer Giuseppe Fabbrini set the libretto to music for an opera staged at the theater of the Collegio Tolomei in Siena. Although the music of the opera is lost, the remark, "Il Sign. Giuseppe Fabrini, che ha data l'anima al verso con l'armonia della musica ..." in the preface of the libretto confirms Fabbrini's setting it to music. Concerning Fabbrini's operas, the Grove Music states that, "His operas to librettos by Gigli were all written for the college theatre which opened in 1685." The opera "La Genefieva" premiered that same year in February.

Libretto of the opera "Roland" by Philippe Quinault; he based the plot of Roland on medieval legends of chivalry, setting episodes from Ludovico Ariosto's epic poem "Orlando furioso." Roland centers on the conflict between duty and love and the intervention of goddesses. This copy includes includes handwritten annotations of performers' names, and a frontispiece engraving undersigned by Jean Dolivar (i.e., Juan Dolivar) that illustrates one of the scenes from the opera. Jean-Baptiste Lully composed the music of the opera which premiered on January 8, 1685.
