In the pastoral landscapes of the Geogics (particularly in this poem’s opening invocation), in the Eclogues , and in some descriptions of the Aeneid , for example when Aeneas visits the site of Rome with Evander (Verg., A. VIII 306-368), gods are present in nature, in the wild space, in the fields ; and the Roman feels the presence of undefined divinities. The pastoral and agricultural themes include many gods of the countryside and of agricultural life; Virgil calls them agrestum praesentia numina (G. I 10). This paper will focus on such divinities as Faunus, Pan and Silvanus. Links have been established between these divinities by way of interpretatio , especially between Faunus and the Greek god Pan. Faunus is present in the religious calendar of Rome ( Lupercalia ); the worship of Silvanus is also well attested in the Roman world. The concept of di agrestes, well attested in Virgil’s works, helps us to define a special category of gods, living in a special area, between civilization and wild space. Some of these divinities combine human and animal features.
