The Irish had, however, another system of writing which they themselves invented. This was the celebrated Ogam script, consisting of a number of short lines, straight or slanting,[5] and drawn either below, above, or through one long stem-line, which stem-line is generally the angle between two sides of a long upright rectangular stone. These lines represented letters; and over two hundred stones have been found inscribed with Ogam writing. It is a remarkable fact that rude as this device for writing is, it has been applied with considerable skill, and is framed with much ingenuity. For in every case it is found that those letters which, like the vowels, are most easily pronounced, are also in Ogam the easiest to inscribe, and the simpler sounds are represented by simpler characters than those that are more complex. To account for the philosophical character of this alphabet[6] "than which no simpler method of writing is imaginable," a German, Dr. Rethwisch, who examined it from this side, concluded that "the natural gifts of the Celts and their practical genius for simplicity and observation ripened up to a certain stage far earlier than those of their Indo-European relations." This statement, however, rests upon the as yet unproved assumption that Ogam writing is pre-Christian and pagan. What is of more interest is that the author of it supposed that with one or two changes it would make the simplest conceivable universal-alphabet or international code of writing. It is very strange that nearly all the Irish Ogam stones are found in the south-west, chiefly in the counties of Cork and Kerry, with a few scattered over the rest of the country--but one in West Connacht, and but one or two at the most in Ulster. Between twenty and thirty more have been found in Wales and Devonshire, and one or two even farther east, thus bearing witness to the colonies planted by the Irish marauders in early Britain, for Ogam writing is peculiar to the Irish Gael and only found where he had settled. Ten stones more have been found in Scotland, probably the latest in date of any, for some of these, unlike the Irish stones, bear Christian symbols. Many Ogams have been easily read, thanks to the key contained in the Book of Ballymote; thanks also to the fact that one or two Ogams have been found with duplicates inscribed in Latin letters. But many still defy all attempts at deciphering them, though numerous efforts have been made, treating them as though they were cryptic ciphers, which they were long believed to be. That Ogam was, as some assert, an early cryptic alphabet, and one intended to be read only by the initiated, is both in face of the numbers of such inscriptions already deciphered and in the face of the many instances recorded in our oldest sagas of its employment, an absurd hypothesis. It is nearly always treated in them as an ordinary script which any one could read. It may, however, have been occasionally used in later times in a cryptic sense, names
