Two ancient pastoral poems were published by Hermann Hagen in 1869 from a manuscript at Einsiedeln and were soon dated to the reign of Nero. In this study, I show that these poems are related to the Bucolicon Olybrii listed in a library catalogue of Murbach from around 850, and demonstrate on internal and external grounds that the poems were likely composed around the end of the fourth century by Anicius Hermogenianus Olybrius, the consul of 395. This attribution enhances our understanding of the literary culture of the age of Claudian and contributes to the on-going debate on the extent and import of Neronian literature.
