to Strabo[43] they fled to Epidaurus. Pausanias[44] mentions that between Tiryns and the gulf are the "θάλαμοι" of the insane daughters of Prœtus, of which no vestige is to be seen now; they cannot have been underground buildings on account of the morass. Theophrastus[45] speaks of the laughing propensities of the Tirynthians, which rendered them incapable of serious work.[46] The myth of the birth of Hercules at Tiryns and the twelve labours he performed for Eurystheus, the king of the neighbouring Mycenæ, may, I think, be easily explained by his double nature as hero and as sun-god.[47] As the most powerful of all heroes, it is but natural that he should be fabled to have been born within the most powerful walls in the world, which were considered as the work of supernatural giants. As sun-god he must have had numerous sanctuaries in the plain of Argos and a celebrated cultus at Tiryns, because the marshy lowlands by which it is surrounded, and which even at present are nearly unproductive from want of drainage, were in remote antiquity nothing but deep swamps and morasses, which extending far up the plain engendered pestilential fevers, and could only be made to disappear gradually by incessant human labour and by the beneficent influence of the sun. For the existence of the immense morasses in the plain of Argos we have no less an authority than Aristotle, who says,[48] "At the time of the Trojan war, the land of Argos being swampy, it could only feed a scanty population, whilst the land of Mycenæ was good and was therefore highly prized. But now the contrary is the case, for the latter has become too dry and lies untilled, whilst the land of Argos, which was a morass and therefore lay untilled, has now become good arable land." Thus it will appear but natural that Hercules, as sun-god, should be fabled to have performed for Eurystheus, the king of Mycenæ, who possessed the whole plain of Argos, the twelve labours which have been long known to mean nothing else than the twelve signs of the zodiac, through which the sun appears to pass in the annual revolution of our globe. The topography of the plain south of Tiryns appears not to have changed since the time of Aristotle, for the northern shore of the gulf consists of deep swamps, which even now extend for nearly a mile inland. [Sidenote: BEGINNING OF WORK AT TIRYNS.] I perfectly agree with the common opinion that the Cyclopean walls of Tiryns are the most ancient monument in Greece; but, having the conviction that no city or fortress wall can be more ancient than the most ancient pottery of the site it surrounds, I was very anxious to investigate the chronology of the Tirynthian walls by systematic excavations. I therefore proceeded to Tiryns on the 31st ultimo, in company with Mrs. Schliemann and my esteemed friends, Castorches, Phendikles and Pappadakes, Professors of Archæology in the University of Athens.
