Overview: This Historical Note attempts to correct oversights in the professional literature by introducing the ancient karst-related writings of Pausanias, a Romanized Greek geographer who lived during the second century AD. Karstic waters were reliably described by several ancient Greek and Latin writers prior to the third century. These writers have been recognized in historical retrospectives of karst science. But even though Pausanias provides the most numerous and diverse descriptions of local waters in karstic terrains, his travelogues and associated documentation of myths do not receive the attention they deserve. As shown in several examples, his narratives contain nuggets of hydrogeological truths even when observations of natural waters were intertwined with ancient theories, seemingly fantastic attestations, and mythological embellishments.
“Ancient Greek Hydromyths About the Submarine Transport of Terrestrial Fresh Water Through Seabeds Offshore of Karstic Regions”
Acta Carsologica Vol. 38, No. 2-3, Postojna 2009, Pages 293-302
Overview: This paper examines the relationship between ancient Greek texts and the physical possibility of focused, distal flow of terrestrial fresh water through the seabed, particularly offshore of karstic coasts. The plausibility or implausibility of claims in four ancient narratives was assessed in the context of modern reports indicating that seabed pathways can transport continental fresh water up to 60 km offshore. These documented cases validated ancient claims of nearshore submarine groundwater transport and legitimized transoceanic claims as mythologized extrapolations of local karst hydrogeology. As submarine groundwater becomes increasingly important in understanding materials transport and identifying potentially exploitable coastal water supplies, ancient stories from past civilizations may give clues to offshore sites meriting further exploration.
“Karst Hydrology in Ancient Myths from Arcadia and Argolis, Greece”
Acta Carsologica Vol 38, No. 1, Postojna 2009, Pages 145-154
Overview: This paper integrates karst hydrology with ancient travelogues and myths describing natural features in the Greek Peloponnese. The history of karst science can be enriched by recognizing the hydrogeological relevance of ancient literary narratives…Some accounts stemmed from an ancient religious practice of throwing items into waterbodies, including karstic structures, to propitiate the water deities. When smaller offerings were suctioned underground into karstic conduits, they could reappaear with resurgent surface waters a considerable distance away from the place of offering. By accidentally or deliberately conducting these rudimentary water traces, ancient observers were able to accurately describe subterranean connections between karst sinkholes, poljes, rivers, and springs.
