Las , or Laas , or La , was one of the most ancient towns of Laconia, located on the western coast of the Laconian Gulf. It is the only town on the coast mentioned in the Periplus of Pseudo-Scylax between Taenarus and Gythium. The Periplus speaks of its port; but, according to Pausanias, the town itself was distant 10 stadia from the sea, and 40 stadia from Gythium. In the time of Pausanias the town lay in a hollow between the three mountains, Asia, Ilium, and Cnacadium; but the old town stood on the summit of Mt. Asia. The name of Las signified the rock on which it originally stood. It is mentioned by Homer in the Catalogue of Ships in the Iliad, and is said to have been destroyed by the Dioscuri, who hence derived the surname of Lapersae. There was also a mountain in Laconia called Lapersa.
