9. A small valley in the district of Elimeia, which lay to the north towards the Illyrian Dassaretians,(1921) was inhabited by the Orestian Macedonians,(1922) who doubtless were so called from the _mountains_ (ὄρη) in which they dwelt, and not from _Orestes_, the son of Agamemnon. The valley of Orestis(1923) contained a lake, in which was the town Celetrum, situated on a peninsula.(1924) Its position coincides with that of the modern Castoria;(1925) and it cannot be doubted that the wild mountain-valley near the source of the Haliacmon was the ancient Orestis. Another valley in Elimeia was called ALMOPIA, or Almonia, an ancient settlement of the Minyans, situated on the confines of Macedonia and Thessaly, apparently not far from Pieria.(1926) 10. Elimeia, together with the surrounding highlands, was cold and rugged, and difficult of cultivation.(1927) The same was the case with the neighbouring district of LYNCESTIS, the country of the Lyncestæ, who had received their name, according to a Macedonian inflexion,(1928) from Lyncus.(1929) Lyncus was the name of the whole district, and not of any one city, as in early times there were only unfortified villages in this part.(1930) It was surrounded on all sides by mountains; a narrow pass between two heights being the chief road to the coast.(1931) The position of Lyncus is accurately determined by the course of the Egnatian Roman road from Dyrrachium, which, after crossing the Illyrian mountains at Pylon (or the gateway), led by Heraclea Lyncestis, and through the country of the Lyncestæ and Eordians, to Edessa and Pella;(1932) as well as by the fact that the _mons Bora_ of Livy, _i.e._ the Bermius, lay to the south of it.(1933) Consequently the Lyncestæ must have inhabited the mountains south of the Erigon, and a part of the valley in which that river flowed; which is confirmed by other accounts of ancient writers.(1934) The country of the EORDIANS is also determined by the direction of the Egnatian way; viz., to the east of Lyncus and west of Edessa, and therefore in the valley of the Lydias, to the north of Elimea(1935) and the Bermius.(1936) In order to go from the valley of the Erigon to Thessaly, the way passed first through Eordæa and then through Elimiotis.(1937)
