a country of Greece, whose boundaries have been different at different periods. Properly speaking, Thessaly was bounded on the south by the southern parts of Greece, or Graecia Propria; east, by the Ægean; north, by Macedonia and Mygdonia; and west, by Illyricum and Epirus. It was generally divided into four separate provinces, Thessaliotes, Pelagiotis, Iliotissi, and Phthiotis, to which some add Magnesia. It has been severally called Æmonia, Peliæicum, Argot, Hellas, Argeia, Dryopis, Pelopidia, Pyrrhœa, &c. The name of Thessaly is derived from Lempris-Thessalus, one of its monarchs. Thessaly is famous for its deluge which happened there in the age of Deucalion. Its mountains and cities are also celebrated, such as Olympus, Pelion, Ossa, Larissa, &c. The Argonauts were partly natives of Thessaly. The inhabitants of the country passed for a treacherous nation, so that false money was called Thessalian coin, and a perfidious action a Thessalian deceit. Thessaly was originally governed by kings, till it became subject to the Macedonian monarchs. The cavalry was universally esteemed, and the people were superstitious and addicted to the study of magic and incantations. See Lucan, lib. vi. ver. 438, &c.; Dionys. i. 219; Curt. lib. iii. cap. 2; Aelian, Var. Hist. lib. iii. cap. 1; Paul. lib. iv. cap. 36; lib. x. cap. 1; Mela, lib. ii. cap. 3; Justin, lib. vii. cap. 6; Diod. iv.

Thessaly is now called Janina, a province of European Turkey, bounded by Macedonia on the north, by the Archipelago on the east, by Achaia or Livadia on the south, and by Epirus on the west.
