It was the Egyptians who first symbolized ideas, and that by the figures of animals. These records, the most ancient of all human history, are still seen engraved on stone. The Egyptians also claim to have invented the alphabet, which the Phœnicians, they say, by means of their superior seamanship, introduced into Greece, and of which they appropriated the glory, giving out that they had discovered what they had really been taught. Tradition indeed says that Cadmus, visiting Greece in a Phœnician fleet, was the teacher of this art to its yet barbarous tribes. According to one account, it was Cecrops of Athens or Linus of Thebes, or Palamedes of Argos in Trojan times who invented the shapes of sixteen letters, and others, chiefly Simonides, added the rest. In Italy the Etrurians learnt them from Demaratus of Corinth, and the Aborigines from the Arcadian Evander. And so the Latin letters have the same form as the oldest Greek characters. At first too our alphabet was scanty, and additions were afterwards made. Following this precedent Claudius added three letters, which were employed during his reign and subsequently disused. These may still be seen on the tablets of brass set up in the squares and temples, on which new statutes are published.
