12. South of Achaia was the central region of Arcadia, surrounded by a ring of mountains, and completely encompassed by the other states of the Peloponnesus. Next to Laconia it was the largest of the ancient divisions of Greece, and the most picturesque and beautiful portion (not unlike Switzerland in its mountain character), and without either seaports or navigable rivers. It was inhabited by a people simple in their habits and manners, noted for their fondness for music and dancing, their hospitality, and pastoral customs. With the poets Arcadia was a land of peace, of simple pleasures, and untroubled quiet; and it was natural that the pipe-playing Pan should first appear here, where musical shepherds led their flocks along the woody vales of impetuous streams. 13. Ar'golis, east of Arcadia, was mostly a rocky peninsula lying between the Saron'ic and Argol'ic gulfs. It was in great part a barren region, with the exception of the plain adjoining its capital city, Argos, and in early times was divided into a number of small but independent kingdoms, that afterward became republics. The whole region is rich in historic associations of the Heroic Age. Here was Tir'yns, whose massive walls were built by the one-eyed Cy'clops, and whence Hercules departed at the commencement of his twelve labors. Here, also, was the Lernæ'an Lake, where the hero slew the many-headed hydra; Ne'mea, the haunt of the lion slain by Hercules, and the seat of the celebrated Ne'mean games; and Myce'næ, the royal city of Agamemnon, who commanded the Greeks in the Trojan War--now known, only by its ruins and its legends of by-gone ages. And still have legends marked the lonely spot Where low the dust of Agamemnon lies; And shades of kings and leaders unforgot, Hovering around, to fancy's vision rise. --HEMANS. 14. At the south-eastern extremity of the Peloponnesus was Laconia, the fertile portions of which consisted mostly of a long, narrow valley, shut in on three sides by the mountain ranges of Ta-yg'etus on the west and Parnon on the north and east, and open only on the south to the sea. Through this valley flows the river Euro'tas, on whose banks, about twenty miles from the sea, stood the capital city, Lacedæ'mon, or Sparta, which was unwalled and unfortified during its most flourishing period, as the Spartans held that the real defence of a town consists solely in the valor of its citizens. The sea-coast of Laconia was lined with towns, and furnished with numerous ports and commodious harbors. While Sparta was equaled by few other Greek cities in the magnificence of its temples and statues, the private houses, and even the palace of the king, were always simple and unadorned.
