Agioi Taxiarches have been constructed on aggraded land. As Pausanias mentions that Elos was a port city, the current Elos cannot be identified with it. Skala, on the other hand, means "place of embarkation." The location of the ancient port, however, is not yet known for certain. Political Legendary pre-Hellenic tribe In Greek legend, the human ancestor of all the peoples that inhabited the Eurotas Valley was Lelex, eponymous king of the Leleges, one of the peoples of the eastern Aegean whom the classical writers saw as autochthonous; that is, indigenous and pre-Hellenic. His son or grandson was Eurotas, the last of the line. The latter had a daughter, Sparta, but no sons. An outsider married her, Lacedaemon. Although he named the state Sparta after her, his name is now known to have most likely been the name of the Mycenaean state. Mycenaean, or late Bronze Age Greece is generally conceded to be Achaean Greek on the evidence of the Linear B and Hittite documents. If any Dorians were present they were not in any capacity overtly recorded by the surviving administrative records; however, most of the records have not survived, so in reality we do not know. Hypothetically, if the Leleges really were in the Eurotas valley, the time of their ascendancy would have been before Mycenaean times. Until the late 20th century, evidence in the valley of earlier occupation seemed to be lacking. Beginning in 1968 the University of Cambridge began a survey by underwater archaeology of a drowned town between Pounta on the mainland and Elafonisos island on the eastern side of the Laconian Gulf. The town extended over the entire drowned isthmus from 60 rock-cut tombs on the Pounta shore (a beach) to the remains of walls on Pavlopetri island off Elafonisos. A subsequent survey in 2009 discovered even earlier parts of the town and recovered additional pottery. A chronological study was done on "442 ceramic items, an iron nail and an obsidian chip." More research on the site is planned. The town was apparently continuously occupied from the late Neolithic to Byzantine times when it was drowned, perhaps by an earthquake. Neolithic ceramics were only 3% of the 444 items. The town was mainly Early Bronze Age, which had 40%. The early Helladic pottery is "standard ... some showing close links with the Cyclades, western Crete and the northeastern Aegean." The "15% Middle Bronze Age"
