Simplified map of the Peloponnesus with critical regions of the “Phyllite Problem” noted: 1. Tyros, 2. Vresthena, 3. Feneos, 4. Kastanitsa, 5. Mercouri, 6. Doliana (after Lekkas and Papanikolaou, 1977). In archaeological terms, a source location of the Tyros Beds for the eaves on the Lernean House of Tiles (Lerna III: Phase D [Late EH II]) represents exploration of another physical environment for the Early Helladics at Lerna.
