Similes in Apollonius’ Argonautica tell two contrasting tales. On the one hand, humans with skilled expertise can exert an exhilarating amount of control over the world around them. The power of knowledge reflects the contemporary culture of Hellenistic Alexandria where new forms of knowledge were sprouting up everywhere. But such skills are largely useless for women, and they fail in the face of human passions. While characters in the simile world of the Argonautica use strategy to overcome danger in a way that is largely out of reach in the Homeric simile world, similes also highlight the intractable power of erotic desire as powerful and deadly as the battlefield of the Iliad. The Argonautica represents the first post-Homeric chapter in the story of epic similes. Simile structures take on a range and variety that previously was found only in the content of the similes. These new forms bring forward simile features that are peripheral in Homeric to reshape the epic genre in ways that reflect the ideas of the Hellenistic period. At moments of powerful emotion in the Argonautica, similes weave “erudition” and “emotion” inextricably together.
