There were a number of such alphabets in the Mediterranean differing widely from each other.[134] It may be noted that the Phœnician alphabet (and perhaps others) omitted vowels. Possibly they pronounced their consonants very hard and had rather indeterminate vowels, as is said to be still the case with tribes of South Arabia. Quite probably, too, the Phœnicians used their alphabet at first not so much for writing as for single initial letters in their business accounts and tallies. One of these Mediterranean alphabets reached the Greeks, long after the time of the Iliad, who presently set to work to make it express the clear and beautiful sounds of their own highly developed Aryan speech. It consisted at first of consonants, and the Greeks added the vowels. They began to write for record, to help and fix their bardic tradition.... § 4 So it was by a series of very natural steps that writing grew out of the life of man. At first and for long ages it was the interest and the secret of only a few people in a special class, a mere accessory to the record of pictures. But there were certain very manifest advantages, quite apart from the increased expressiveness of mood and qualification, to be gained by making writing a little less plain than straightforward pictures, and in conventionalizing and codifying it. One of these was that so messages might be sent understandable by the sender and receiver, but not plain to the uninitiated. Another was that so one might put down various matters and help one’s memory and the memory of one’s friends, without giving away too much to the common herd. Among some of the earliest Egyptian writings, for example, are medical recipes and magic formulæ. Accounts, letters, recipes, name lists, itineraries; these were the earliest of written documents. Then, as the art of writing and reading spread, came that odd desire, that pathetic desire so common among human beings, to astonish some strange and remote person by writing down something striking, some secret one knew, some strange thought, or even one’s name, so that long after one had gone one’s way, it might strike upon the sight and mind of another reader. Even in Sumeria men scratched on walls, and all that remains to us of the ancient world, its rocks, its buildings, is plastered thickly with the names and the boasting of those foremost among human advertisers, its kings. Perhaps half the early inscriptions in that ancient world are of this nature, if, that is, we group with the name-writing and boasting the epitaphs, which were probably in many cases prearranged by the deceased.
