In the late fifth century BCE, traditional religious beliefs and practices were being reconsidered from a variety of intellectual fields and viewpoints, but perhaps most vigorously interrogated by the Sophists. Although ancient Greek religion was characteristically open to change and local variety, the Sophists and contemporaneous thinkers put this flexibility to the test, as ancient reports of trials against intellectuals on account of their religious views attest. Anaxagoras and Socrates, in different ways, offer novel perspectives on what the divine is and is not; Protagoras in one way and the Derveni author in another question traditional certainties about our access to and knowledge of the divine; Prodicus, Democritus, and the so-called Sisyphus fragment provide psychological and/or sociological explanations of religious beliefs; and characters in plays by Euripides and Aristophanes deny outright the existence of the gods and, with that, the existence of traditional moral values.

This chapter examines the Derveni papyrus and compares its hermeneutics to exegetic techniques found in cuneiform texts. The analysis shows that the anonymous author of the papyrus operates with semantic and theological models that align with ideas expressed in Akkadian texts, particularly those ideas relating to theonyms and the evolution of the cosmos. As in some Assyrian and Babylonian texts, the author makes use of hermeneutic techniques that heavily rely on morphological analysis aiming to prove that divine names have a unified referent. This referent is a polyonymous cosmic god, Nous (Mind), which has the same characteristics of the Babylonian gods Ninurta and Marduk when represented as universalizing divinities of multiple names.

In the seventh and last chapter of De mundo, the author discusses the many names of God, which reflect the various effects God produces in the world (401a12–27). In line with the predominantly Aristotelian background of the author, it is claimed that these effects are not caused by God directly, but by his power (dunamis). This approach helps explain various traditional names, epithets and functions assigned to Zeus in Greek religion and mythology, including names which refer to meteorological phenomena and epithets related to cosmology, but also, perhaps more surprisingly, to human affairs. In this respect, as a detailed comparison shows, the chapter is clearly inspired by various Stoic authors. The central place of the chapter is occupied by the famous Orphic hymn to Zeus. A detailed interpretation of the hymn shows that it is in many ways compatible with the philosophical outlook of De mundo. However, the hymn also features parallels with the Orphic theogony commented upon in the Derveni Papyrus and its later version, which was quoted by late Neoplatonists. The comparison reveals various similarities and differences between these three texts and supports a hypothesis according to which the author of De mundo omitted some parts of the original Orphic theogony. Traces of the missing verses, however, can be seen in the subsequent section (401b8–29), where Fate is discussed. This interconnection helps us to better understand both De mundo and the Derveni Papyrus.
