This interdisciplinary article argues that ancient Greek and Roman representations of Okeanos, Tartaros, and the underworld demonstrate an observational awareness of the hollow underground spaces that characterize the geomorphology of karst terrains in the Mediterranean world. We review the scientific facts that underlie Greek and Roman accounts of karstic terrain in observation-based discourse and in myths, and we demonstrate that the Greek words barathron (pit), limnē (lake), koilos (hollow), and dinē (whirling current) are used with precision in observational accounts of karst terrain. Ancient accounts of the dynamic limnē and barathrum systems characteristic of much karst terrain offer a complex matrix of observation-based and belief-based discourse: at the edge of the barathrum, the imaginative or spiritual realm of the underworld has a material plausibility and the closely observed material world has a plausible potential to connect to a world we cannot see.

This essay explores references to monkeys as a way of talking about imitation, authenticity, and identity in Greek stories about the ““Monkey Island”” Pithekoussai (modern Ischia) and in Athenian insults, and in Plautus' comedy. In early Greek contexts, monkey business defines what it means to be aristocratic and authoritative. Classical Athenians use monkeys to think about what it means to be authentically Athenian: monkey business is a figure for behavior which threatens democratic culture——sycophancy or other deceptions of the people. Plautus' monkey imagery across the corpus of his plays moves beyond the Athenian use of ““monkey”” as a term of abuse and uses the ““imitative”” relation of monkeys to men as a metapoetic figure for invention and play-making. For Plautus, imitator——and distorter——of Greek plays, monkeys' distorted imitations of men are mapped not onto the relations between inauthentic and authentic citizens, as in Athens, but onto the relation of Roman to Greek comedy and culture at large. Monkey business in Plautus is part of the insistence on difference which was always crucial in Roman encounters with Greek culture.
