That there had been an alphabet in Greece, prior to the introduction of the Cadmean, or Phoenician,
although a question involved in much obscurity, seems to have been finally determined in the affirmative. In fact, it is difficult to conceive, how a personage so honored in the early history of the times, as Pelasgus, could have been so great a benefactor, without the introduction of an alphabet. He is said to have taught the barbarous inhabitants to clothe themselves in a more comfortable manner; to build houses; to adopt a food more congenial to the nature of the human constitution; to erect temples to the gods. There can be little hesitation in believing, that he also introduced a knowledge of letters; which all the Amonian or Cuthite family carried with them in their migration from the plains of Shinear to Phoenicia, Egypt, Greece, and other parts of the world. The Eugubian Tablet, the oldest profane monument, with written characters, now extant, and engraved—according to the opinion of the ablest scholars—two generations before the war of Troy, contains thirteen single letters; being the facsimile of the Pelasgian characters used in Greece and Italy. Now, allowing the tablet to be engraved, even as late as the Trojan war, still it will be much anterior to Cadmus.
