But this epoch had been preceded by the "Age of the Three [six] Rulers," when people lived in caves, ate wild fruits and uncooked food, drank the blood of animals and wore the skins of wild beasts (our Old Stone Age). Later they grew less rude, learned to obtain fire by friction, and built themselves habitations of wood or foliage (our Early Neolithic Age). Thus is everywhere revealed the background of sheer savagery, which lies behind all human culture, while the "Golden Age" of the poets fades with the "Hesperides" and Plato's "Atlantis" into the region of the fabulous.
Historic Times.
Little need here be said of strictly historic times, the most characteristic feature of which is perhaps the general use of letters. By means of this most fruitful of human inventions, everything worth preserving was perpetuated, and thus all useful knowledge tended to become accumulative. It is no longer possible to say when or where the miracle was wrought by which the apparently multifarious sounds of fully-developed languages were exhaustively analysed and effectively expressed by a score or so of arbitrary signs. But a comparative study of the various writing-systems in use in different parts of the world has revealed the process by which the transition was gradually brought about from rude pictorial representations of objects to purely phonetical symbols.
Evolution of Writing Systems.
As is clearly shown by the "winter counts" of the North American aborigines, and by the prehistoric rock carvings in Upper Egypt, the first step was a pictograph, the actual figure, say, of a man, standing for a given man, and then for any man or human being. Then this figure, more or less reduced or conventionalised, served to indicate not only the term man, but the full sound man, as in the word manifest, and in the modern rebus. At this stage it becomes a phonogram, or phonoglyph, which, when further reduced beyond all recognition of its original form, may stand for the syllable ma as in ma-ny, without any further reference either to the idea or the sound man. The phonogram has now become the symbol of a monosyllable, which is normally made up of two elements, a consonant and a vowel, as in the Devanágari, and other syllabic systems.
Lastly, by dropping the second or vowel element the same symbol, further modified or not, becomes a letter representing the sound m, that is, one of the few ultimate elements of articulate speech. A more or less complete set of such characters, thus worn down in form and meaning, will then be available for indicating more or less completely all the phonetic elements of any given language. It will be a true alphabet, the wonderful nature of which may be inferred from the fact that only two, or possibly three, such alphabetic systems are known with absolute certainty to have ever been independently evolved by human ingenuity[112]. From the above exposition we see how inevitably the Phoenician parent of nearly all late alphabets expressed at first the consonantal sounds only, so that the vowels or vowel marks are in all cases later developments, as in Hebrew, Syriac, Arabic, Greek, the Italic group, and the Runes.
Hieroglyphs and Cuneiforms.
In primitive systems, such as the Egyptian, Sumerian, Chinese, Maya-Quiché and Mexican, one or more of the various transitional steps may be developed and used simultaneously, with a constant tendency to advance on the lines above indicated, by gradual substitution of the later for the earlier stages. A comparison of the Sumerian cuneiform and Egyptian hieroglyphic systems brings out some curious results. Thus at an extremely remote epoch, some millenniums ago, the Sumerians had already got rid of the pictorial, and to a great extent of the ideographic, but had barely reached the alphabetic phase. Consequently their cuneiform groups, although possessing phonetic value, mainly express full syllables, scarcely ever letters, and rarely complete words. Ideographs had given place first to phonograms and then to mere syllables, "complex syllables in which several consonants may be distinguished, or simple syllables composed of only one consonant and one vowel or vice versa[113]."
The Egyptians, on the other hand, carried the system right through the whole gamut from pictures to letters, but retained all the intermediate phases, the initial tending to fall away, the final to expand, while the bulk of the hieroglyphs represented in various degrees the several transitional states. In many cases they "had kept only one part of the syllable, namely a mute consonant; they detached, for instance, the final u from bu and pu, and gave only the values b and p to the human leg
