The Roman Stoic Cornutus, who lived in the age of Nero, is the heir of an ancient and rich Stoic allegorical tradition applied to all aspects of traditional religion: literary myths, cultic epithets and attributes, and even iconographical representations of deities. Allegoresis (allegorical exegesis) was applied in antiquity to culturally and religiously authoritative texts. It was mainly practiced by “pagan” philosophers like Stoics and Middle and Neoplatonists and by philosophically minded Hellenistic Jewish and Christian exegetes, who read Scripture allegorically.Cornutus offers an excellent example of mythological allegoresis in his handbook of Greek theology. For each divinity, from Ouranos to Hades, Cornutus provides an allegorico-etymological interpretation of its names and epithets, its attributes, aspects of its myths and rituals, etc. Physical allegory (Zeus represents the ether, Hera the air, etc.) is prevalent, although there are also examples of ethical and historical exegeses. Special attention is demanded by Cornutus’ programmatic assertion—analysed below—that “The ancients were not people of no account, but they were also able to understand the nature of the cosmos and had the ability to philosophise on it by means of symbols and enigmata” (35). The ancient were nothing less than philosophers, since they were endowed with the understanding of the cosmos, of what exists. What they expressed allegorically are philosophical truths. Philosophical allegoresis interprets their expressions and finds philosophical tenets therein. Cornutus was strongly influenced by Chrysippus, Apollodorus of Athens, and Crates of Mallus, while Seneca, who was a Stoic but no allegorist, probably polemicised with Cornutus.Stoic allegoresis, as practiced by the Stoics Cornutus and Chaeremon roughly at the same time, later influenced not only the so-called Middle Platonists, but also the Christian Platonist Origen. Origen seems to have applied allegoresis not only to the Bible, like Philo and Clement before him, but also to Plato’s dialogues and myths. All these allegorisers aimed at finding deeper meanings and philosophical truths in traditional accounts, thereby rescuing them from accusations of superficiality or impiety. The goal was to find in ancient poets and other expressions of traditional religion, as well as in Scripture, meanings “worthy of the divine.” Remarkable structural similarities between the Stoic allegorical tradition inherited by Cornutus and Origen’s allegoresis will be pointed out.
