It has long been acknowledged that it is from Egypt that our earliest specimens of glass have come. But until quite recently the greatest misconceptions have prevailed as to the age and the methods of preparation of Egyptian glass. Misled by an erroneous interpretation of what are probably representations of metallurgical processes, on the walls of Twelfth Dynasty tombs at Beni Hassan and elsewhere, it was inferred that the art of blowing glass was known to the Egyptians at least as long ago as the days of the Middle Empire; by others the art was carried back to a still earlier period. We now have almost full assurance that glass in a true sense was practically unknown to the Egyptians before the time of the Eighteenth Dynasty (say between 1600 and 1500 B.C.),[7] and that for at least a thousand years after that period all that was made was produced by a primitive process in which the blowing-iron found no part. We have, unfortunately, up to the present time absolutely no evidence to show in what country or at what date this new process—I mean the blowing of a vesicle of glass—first came into use. There is, as we shall see, some reason to look for it rather in Western Asia than in Egypt, but the important point to bear in mind is that it was only after the introduction of this process of blowing, first to Alexandria and then to the Rome of the early empire, that the employment of glass for objects of daily use became in any way general. Glass, indeed, in these early days, whether in Egypt or in the Greek world of the Mycenæan age, was something very different from what we now understand by the term. We must ‘think away’ a great deal of the modern connotation of the word. We must, above all, think of the material in connection with the native precious or semi-precious stones that it more or less resembled, and which were used along with it for decorative purposes. We do not know the Egyptian name for glass, but probably, like the Greeks, they divided all the hard stony bodies used in the arts into such as were ‘dug up’—natural products, that is, which they found ready at hand—and such as had been artificially prepared, and above all previously melted (the Λίθος όρωρυγμένη on the one hand, and the Λίθος χυτή on the other).
