Aurea aetas is Ovid's term in the Metamorphoses (Book I) for the first and most perfect of
the four mythological ages (gold, silver, bronze, iron). Students should note that Hesiod's original Greek version in Works and Days is slightly different — he inserts a fifth age of
heroes between bronze and iron — and that different poets appropriate different versions depending on their thematic needs. The nostalgia for aurea aetas in poetry is not simply naïve primitivism: it is a critical tool that uses the mythological ideal to expose the deficiencies of
the present. The phrase is also connected to millenarian and utopian traditions in poetry — the hope that
the golden age might return, which appears in Virgil's Fourth Eclogue (interpreted by Christians as
a prophecy of Christ) and in Romantic revolutionary poetry. Related terms include locus amoenus (the pleasant place), Arcadia, and the pastoral mode.
