GLASS MANUFACTURE.—The manufacture of glass, a discovery usually attributed to the Phoenicians, [Footnote: The Phoenicians, being the carriers of antiquity, often received credit among the peoples with whom they traded, for various inventions and discoveries of which they were simply the disseminators.] was carried on in Egypt more than four thousand years ago. The paintings of the monuments represent glass-blowers moulding all manner of articles. Glass bottles, and various other objects of the same material, are found in great numbers in the tombs. Some of these objects show that the ancient Egyptians were acquainted with processes of coloring glass that secured results which we have not yet been able to equal. The Egyptian artists imitated, with marvellous success, the variegated hues of insects and stones. The manufacture of precious gems, so like the natural stone as to defy detection, was a lucrative profession.

THE PAPYRUS PAPER.—The chief writing material used by the ancient Egyptians was the noted papyrus paper, manufactured from a reed which grew in the marshes and along the water-channels of the Nile. From the Greek names of this Egyptian plant, byblos and papyrus, come our words "Bible" and "paper." The plant has now entirely disappeared from Egypt, and is found only on the Anapus, in the island of Sicily, and on a small stream near Jaffa, in Palestine. Long before the plant became extinct in Egypt an ancient prophecy had declared, "The paper reeds by the brooks … shall wither, be driven away, and be no more." (Isa. xix. 7.) The costly nature of the papyrus paper led to the use of many substitutes for writing purposes—as leather, broken pottery, tiles, stones, and wooden tablets.

FORMS OF WRITING.—The Egyptians employed three forms of writing: the hieroglyphical, consisting of rude pictures of material objects, usually employed in monumental inscriptions; the hieratic, an abbreviated or rather simplified form of the hieroglyphical, adapted to writing, and forming the greater part of the papyrus manuscripts; and the demotic, or encorial, a still simpler form than the hieratic. The last did not come into use till about the seventh century B.C., and was then used for all ordinary documents, both of a civil and commercial nature. It could be written eight or ten times as fast as the hieroglyphical form.

KEY TO EGYPTIAN WRITING.—The key to the Egyptian writing was discovered by means of the Rosetta Stone. This valuable relic, a heavy block of black basalt, is now in the British Museum. It holds an inscription, written in hieroglyphic, in demotic, and in Greek characters. Champollion, a French scholar, by comparing the characters composing the words Ptolemy, Alexander, and other names in the parallel inscriptions, discovered the value of several of the symbols; and thus were opened the vast libraries of Egyptian learning.

We have now the Ritual, or Book, of the Dead, a sort of guide to the soul in its journey through the underworld; romances, and fairy tales, among which is "Cinderella and the Glass Slipper"; autobiographies, letters, fables, and epics; treatises on medicine, astronomy, and various other scientific subjects; and books on history—in prose and verse—which fully justify the declaration of the Egyptian priests to Solon: "You Greeks are mere children, talkative and vain; you know nothing at all of the past."

ASTRONOMY, GEOGRAPHY AND ARITHMETIC.—The cloudless and brilliant skies of Egypt invited the inhabitants of the Nile valley to the study of the heavenly bodies. And another circumstance closely related to their very existence, the inundation of the Nile, following the changing cycles of the stars, could not but have incited them to the watching and predicting of astronomical movements. Their observations led them to discover the length, very nearly, of the sidereal year, which they made to consist of 365 days, every fourth year adding one day, making the number for that year 366. They also divided the year into twelve months of thirty days each, adding five days to complete the year. This was the calendar that Julius Cæsar introduced into the Roman Empire, and which, slightly reformed by Pope Gregory XIII. in 1582, has been the system employed by almost all the civilized world up to the present day.

The Greeks accounted for the early rise of the science of geometry among the Egyptians by reference to the necessity they were under each year of re-establishing the boundaries of their fields—the inundation obliterating old landmarks and divisions. The science thus forced upon their attention was cultivated with zeal and success. A single papyrus has been discovered that holds twelve geometrical theorems.

Arithmetic was necessarily brought into requisition in solving astronomical and geometrical problems. We ourselves are debtors to the ancient Egyptians for much of our mathematical knowledge, which has come to us from the banks of the Nile, through the Greeks and the Saracens.

MEDICINE AND THE ART OF EMBALMING.—The custom of embalming the dead, affording opportunities for the examination of the body, without doubt had a great influence upon the development of the sciences of anatomy and medicine among the Egyptians. That the embalmers were physicians, we know from various testimonies. Thus we are told in the Bible that Joseph "commanded the physicians to embalm his father." The Egyptian doctors had a very great reputation among the ancients.

Every doctor was a specialist, and was not allowed to take charge of cases outside of his own branch. As the artist was forbidden to change the lines of the sacred statues, so the physician was not permitted to treat cases save in the manner prescribed by the customs of the past; and if he were so presumptuous as to depart from the established mode of treatment, and the patient died, he was adjudged guilty of murder. Many drugs and medicines were used; the ciphers, or characters, employed by modern apothecaries to designate grains and drams are of Egyptian invention.
