Pentelicus which he interpreted as a message to the Persians, marched back the victorious army in time to defend Athens. The enemy, upon noticing his presence, did not venture a second disembarcation and retired straightway out of Greek waters. The details of the battle, and the Persian plan of campaign, are not made clear by our ancient sources, but reconstructions have been attempted by numerous modern authorities. (M. O. B. C.) The tumulus or "Soros" was excavated by M. Stais in 1891 and 1892. A slight previous excavation had brought to light some prehistoric implements, and it was supposed that the mound had no connexion with the battle; but it has now been discovered that the presence of those prehistoric objects was accidental. Underlying the mound was found a stratum about 85 ft. long by 20 broad, consisting of a layer of sand, above which lay the ashes and bones of many corpses; together with these were the remains of many lecythi and other vases, some of them contemporary with the Persian wars, some of them of much earlier style, and probably taken in the emergency from neighbouring cemeteries. It is conjectured with some probability that a large vase containing ashes may have been used as the burial urn of one of the Athenian generals who fell. There was also, in the middle of the stratum, a trench for funeral offerings about 30 ft. by 3; it contained bones of beasts, with ashes and fragments of vases. There can therefore be no doubt that the tumulus was piled up to commemorate the Athenians who fell in the battle, and that it marks the place where the carnage was thickest. A selection from the contents of the tumulus has been placed in the National Museum at Athens. (E. Gr.) See Herodotus vi. 102-117; W. M. Leake, _The Topography of Athens_ (London, 1841), ii. 203-227; R. W. Macan, _Herodotus_, iv.-vi. (London, 1895), ii. 149-248; G. B. Grundy, _The Great Persian War_ (London, 1901), pp. 145-194; J. A. Munro in _Journal of Hellenic Studies_, 1899, pp. 186-197. For the tumulus, [Greek: Harchaiologikon Aeltion] 1891, pp. 67 sqq. See also MILTIADES. MARAZION, a small seaport in the St Ives parliamentary division of Cornwall, England, on the shore of Mount's Bay, 2 m. E. of Penzance, served by the Great Western railway. Pop. (1901), 1251. A causeway of boulders and pebbles, thrown up by the sea and passable at low tide, unites Marazion with the insular St Michael's Mount (q.v.). The church of St Hilary, destroyed by fire in 1853, had a very fine spire, which has been faithfully reproduced in the restored building. Unusual archaeological interest attaches to the churchyard. Its inscribed stones date from the 4th century, one being in honour of Constantine the Great. Another has Cornish lettering, which can no longer be deciphered; and there are British and Roman crosses. Market gardening and fishing are the main industries.
