Sentence:  {1} Who first surrounded the <WSD>Acropolitan</WSD> platform with a wall, is unknown, but it is probable that the work of Pelasgi may be traced in part of the boundary wall, from a division of it having received that name by tradition. / {2} The walls of Tiryns and Mycenæ, are the finest remains of <WSD>Acropolitan</WSD> building in Greece, but they are inferior in magnitude to erections, (called Cyclopean), of Norba, in Latium; and several other Pelasgic fortresses of Cora, Signia, and Alatrium, in Italy, (the walls of which resemble those of Tiryns, Argos, and Mycenæ,) whose wonderful ruins exhibit walls of equal strength and solidity with those of Argolis. 
Meaning of the word marked with <WSD> tags:  Of, pertaining to, or in the style of the Athenian Acropolis; compare (acropolitan).
