LXXII. GLAUCUS’S LEAP.—Immediately beyond the flat-topped hillock which probably marks the site of Salganeus, the plain comes abruptly to an end and the path runs along the steep, bushy, but not precipitous slope of Mount Messapius at some height above the sea, which on a bright sunshiny day is of a beautiful green colour, clear as crystal and dappled with patches of purple. Thus proceeding along the steep mountain-side for about a mile we find ourselves opposite a pretty rocky island, wooded with pines, which lies a little way off the shore. On the island is a ruin which, so far as I could judge by the eye from the shore, seemed to be mediaeval or modern. Hereabouts, too, a row of large stones may be observed lying at the bottom of the clear water, but they appear to be boulders rather than hewn stones. Farther on a high cliff, which seen from the east reminds one of the Lorelei Rock on the Rhine, rises close to the shore. The path here descends and runs along the narrow beach at the foot of the cliff, from which a very copious spring of water rushes into the sea. This high cliff is probably what the ancients called Glaucus’s Leap. On the morning when I passed it, the clear, sunlit, greenish-blue water at its foot looked very inviting; one could fancy the sea-god taking his plunge into its cool delicious depths. Beyond the cliff the path again runs along the foot of the long slope, covered with lentisk and holly-oak bushes, which descends from the high, bold, pointed summit of Mount Messapius in an unbroken sweep to the sea. LXXIII. EVENING ON THE EURIPUS.—The views from Anthedon across the beautiful Euripus are charming, especially at sunset when the opposite mountains of Euboea glow with delicate pink and lilac hues, and flakes of golden and rosy clouds are reflected in the mirror-like surface of the strait, which, apparently landlocked on all sides, resembles a calm lake. The effect is heightened if a fishing-boat, its russet sails aglow in the warm evening light, chances to glide along at the time, and a snatch of song comes wafted from it across the water. LXXIV. THE COPAIC LAKE.—Like other lakes which are drained not by rivers but by natural subterranean passages in the limestone mountains which surround them, the level of the Copaic Lake varied greatly from time to time. Such variations depend upon two different sets of causes, first the varying capacity of the emissaries, and second the varying amount of water poured into the lake.
