The Sibylline Oracles are a collection of prophetic poems written by unknown Jewish and Christian authors over many centuries, from roughly the 2nd century BCE to the 7th century CE. The authors wrote under the name of the Sibyl, a legendary pagan prophetess from classical antiquity, to give their messages greater authority and reach a wide audience. The provided dating for this specific anonymous entry, the 4th to 6th centuries CE, represents a late, Christian phase of this long tradition.

The surviving corpus consists of 14 books of poetry written in Greek epic verse. It is a composite work where Jewish compositions (most prominent in Books III-V) were later expanded and edited by Christian writers. The poems adapt a pagan literary form to convey Jewish and Christian themes, such as monotheism, future judgment, and critiques of pagan empires like Rome.

According to modern scholars, the Oracles are a major example of cross-cultural religious propaganda in the ancient world. Their significance lies in this deliberate synthesis, showing how Jewish and Christian communities used a familiar pagan genre to promote their theology and ethics. Early Christian authors often quoted them as prophetic support for their faith. The collection is valued today as important evidence for the history of apocalyptic ideas and the complex interactions between different religious traditions in antiquity.
