There are two main routes from the plain of Marathon to Athens; one of them goes by the south, the other by the north side of Mount Pentelicus. The first route leaves the plain at its southern extremity, and passing between the foot of Mount Agrieliki and the marsh of Vrexisa runs parallel with the coast for some distance. It then turns westward, and crossing the deep valley which divides Pentelicus on the north from Hymettus on the south enters the plain of Athens. This is by far the easiest road; it is the only one which vehicles can traverse. The distance by this road from the great mound at Marathon to Athens is about twenty-five or twenty-six miles. The other route, by the north side of Mount Pentelicus, goes from Oenoe (the modern Ninoi) by a very steep and toilsome path to Stamata, a village in a high situation, surrounded by a few barren fields, among woods of pine. In many places the path is so hemmed in between cliffs and precipices that there is room only for a single horse. Trees are rare, but the stony slopes of the mountain are overgrown with shrubs of many sorts, among which the _Erica arborea_ is conspicuous. In spring its masses of white blossoms perfume the whole air with their fragrance. About half an hour short of Stamata, at a point where there is a spring shaded by fine plane-trees, the path is joined on the left by another path, also steep and toilsome, which comes up from Vrana. This latter path commands a magnificent view backward down the deep ravine through which the traveller has ascended. On either side of the ravine rise the mountains, their precipitous sides covered with straggling pine-forest or evergreen copse, and terminating in bold peaks; below is spread out the green expanse of the Marathonian plain, backed by the sea and Cape Cynosura curving into the blue water with the sweep of a scimitar. Farther off, bounding the prospect, stretches the long line of the mountains of Euboea. From Stamata the path skirts the north-western shoulder of Mount Pentelicus and enters Kephisia, from which there is a good highroad through the plain to Athens. The distance by this route from the mound at Marathon to Athens is roughly about twenty-two miles. A third route, intermediate between the two preceding routes and shorter than either of them, goes from Vrana up the wild romantic ravine of Rapentosa and crosses the southern shoulder of Mount Pentelicus, the highest summit of which is left about a mile to the westward. It is a rugged and precipitous path, hardly practicable even for heavy infantry. Within a distance of little more than nine miles the route ascends and descends a ridge which rises more than two thousand five hundred feet above the plain below.
