We must begin our account with the Thessalians, omitting very ancient and fabulous stories, and what is not generally admitted, (as we have done in other instances,) but propose to mention what appears suited to our purpose. CHAPTER V. 1. The sea-coast, extending from Thermopylæ to the mouths of the Peneius,[483] and the extremities of Pelion, looking towards the east, and the northern extremities of Eubœa, is that of Thessaly. The parts opposite Eubœa and Thermopylæ are occupied by Malienses, and by Achæan Phthiotæ; those towards Pelion by the Magnetes. This may be called the eastern and maritime side of Thessaly. From either side from Pelion, and the Peneius, towards the inland parts are Macedonians, who extend as far as Pæonia, (Pindus?) and the Epeirotic nations. From Thermopylæ, the Œtæan and Ætolian mountains, which approach close to the Dorians, and Parnassus, are parallel to the Macedonians. The side towards the Macedonians may be called the northern side; the other, the southern. There remains the western side, enclosed by Ætolians and Acarnanians, by Amphilochians and Athamanes, who are Epirotæ; by the territory of the Molotti, formerly said to be that of the Æthices, and, in short, by the country about Pindus. Thessaly,[484] in the interior, is a plain country for the most part, and has no mountains, except Pelion and Ossa. These mountains rise to a considerable height, but do not encompass a large tract of country, but terminate in the plains. 2. These are the middle parts of Thessaly, a district of very fertile country, except that part of it which is overflowed by rivers. The Peneius flows through the middle of the country, and receiving many rivers, frequently overflows. Formerly, according to report, the plain was a lake; it is enclosed on all sides inland by mountains, and the sea-coast is more elevated than the plains. When a chasm was formed, at the place now called Tempe, by shocks of an earthquake, and Ossa was riven from Olympus, the Peneius flowed out through it to the sea, and drained this tract of country. Still there remained the large lake Nessonis, and the lake Bœbeis; which is of less extent than the Nessonis, and nearer to the sea-coast. 3. [CAS. 430] Such then is Thessaly, which is divided into four parts, Phthiotis, Hestiæotis, Thessaliotis, and Pelasgiotis. Phthiotis comprises the southern parts, extending along Œta from the Maliac and (or) Pylaïc Gulf[485] as far as Dolopia and Pindus, increasing in breadth to Pharsalia and the Thessalian plains. Hestiæotis comprises the western parts and those between Pindus and Upper Macedonia; the rest is occupied by the inhabitants of the plains below Hestiæotis, who are called Pelasgiotæ, and approach close to the Lower Macedonians; by the [Thessalians] also, who possess the country next in order, as far as the coast of Magnesia.
