Pompeius grammaticus (Fasz. I); Rhetorica ad Herennium (Fasz. II)
The manuscript consists of two originally independent parts: Fascicle I (foll. 1-167: Pompeius grammaticus) was written in 1464 in Heidelberg, fascicle II (foll. 168-191: Rhetorica ad Herennium) was written in the 13th/14th century. Its place of origin is unknown. Whether the codex or one of its parts was ever held in Lorsch is unsure.
