and the towers were improved by making them square. The ancients had no occasion for any form more complete, being sufficient for defending against all the missile weapons at that time known. The invention<167> of cannon required a variation in military architecture. The first cannons were made of iron bars, forming a concave cylinder, united by rings of copper. The first cannon-balls were of stone, which required a very large aperture. A cannon was reduced to a smaller size, by using iron for balls instead of stone; and that destructive engine was perfected by making it of cast metal. To resist its force, bastions were invented, horn-works, crown-works, half-moons, &c. &c.; and military architecture became a system, governed by principles and general rules. But all in vain: it has indeed produced fortifications that have made sieges horridly bloody; but artillery, at the same time, has been carried to such perfection, and the art of attack so improved, that no fortification, it is thought, can be rendered impregnable. The only impregnable defence, is good neighbourhood among weak princes, ready to unite whenever one of them is attacked by a superior force. And nothing tends more effectually to promote such union, than constant experience that fortifications cannot be relied on.<168>
With respect to naval architecture, the first vessels were beams joined together, and covered with planks, pushed along with poles in shallow water, and in deep water drawn by animals on the shore. To these succeeded trunks of trees cut hollow, termed by the Greeks monoxyles. The next were planks joined together in form of a monoxyle. The thought of imitating a fish advanced naval architecture. A prow was constructed in imitation of the head, a stern with a moveable helm in imitation of the tail, and oars in imitation of the fins. Sails were at last added; which invention was so early that the contriver is unknown. Before the year 1545, ships of war in England had no port-holes for guns, as at present: they had only a few cannon placed on the upper deck.
When Homer composed his poems, at least during the Trojan war, the Greeks had not acquired the art of gelding cattle: they eat the flesh of bulls and of rams. Kings and princes killed and cooked their victuals: spoons, forks, table-cloths, napkins, were unknown. They fed sitting, the custom of reclining upon beds being<169> afterward copied from Asia; and, like other savages, they were great eaters. At the time mentioned, they had no chimneys, nor candles, nor lamps. Torches are frequently mentioned by Homer, but lamps never: a vase was placed upon a tripod, in which was burnt dry wood for giving light. Locks and keys were not common at that time. Bundles were secured with ropes intricately combined(a); and hence the famous Gordian knot. Shoes and stockings were not early known among them, nor buttons, nor saddles, nor stirrups. Plutarch reports, that Gracchus caused stones to be erected along the highways leading from Rome, for the convenience of mounting a horse; for at that time stirrups were unknown in Rome, though an obvious invention. Linen for shirts was not used in Rome for many years after the government became despotic. Even so late as the eighth century, it was not common in Europe. We are informed by Herodotus, that the Lydians were reputed to be the first who coined gold and silver money. This was probably after the Trojan war; for during that<170> war the Greeks and Trojans trafficked by barter, as Homer relates: Priam weighs out the ten talents of gold which were the ransom of his son’s body.2
Thales, one of the seven wise men of Greece, about six hundred years before Christ, invented the following method for measuring the height of an Egyptian pyramid. He watched the progress of the sun, till his body and its shadow were of the same length; and at that instant measured the shadow of the pyramid, which consequently gave its height. Amasis King of Egypt, present at the operation, thought it a wonderful effort of genius; and the Greeks admired it highly. Geometry must have been in its cradle at that time. Anaximander, some ages before Christ, made the first map of the earth, as far as then known. About the end of the thirteenth century, spectacles for assisting the sight were invented by Alexander Spina, a monk of Pisa. So useful an invention cannot be too much extolled. At a period of life when the judgment is in maturity, and reading is of great benefit, the eyes begin to grow dim. One cannot help pitying the condition of bookish men<171> before that invention, many of whom must have had their sight greatly impaired, while their appetite for reading was in vigour.
The origin and progress of writing make a capital article in the history of arts. To write, or, in other words, to exhibit thoughts to the eye, was early attempted in Egypt by hieroglyphics. But these were not confined to Egypt: figures composed of painted feathers were used in Mexico to express ideas; and by such figures Montezuma received intelligence of the Spanish invasion: in Peru, the only arithmetical figures known were knots of various colours, which served to cast up accounts. The second step naturally in the progress of the art of writing, is, to represent each word by a mark, termed a letter, which is the Chinese way of writing: they have about 11,000 of these marks or letters in common use; and, in matters of science, they employ to the number of 60,000. Our way is far more easy and commodious: instead of marks or letters for words, which are infinite, we represent by marks or letters, the articulate sounds that compose words: these sounds<172> exceed not thirty in number; and consequently the same number of marks or letters are sufficient for writing. It was a lucky movement to pass at one step from hieroglyphics, the most imperfect mode of writing, to letters representing sounds, the most perfect; for there is no appearance that the Chinese mode was ever practised in this part of the world. With us, the learning to read is so easy as to be acquired in childhood; and we are ready for the sciences as soon as the mind is ripe for them: the Chinese mode, on the contrary, is an unsurmountable obstruction to knowledge; because, it being the work of a lifetime to read with ease, no time remains for studying the sciences. Our case was in some measure the same at the restoration of learning: it required an age to be familiarized with Greek and Latin; and too little time remained for gathering knowledge from books composed in these languages. The Chinese stand upon a more equal footing with respect to arts; for these may be acquired by imitation or oral instruction, without books.
The art of writing with letters representing sounds, is of all inventions the<173> most important, and the least obvious. The way of writing in China makes so naturally the second step in the progress of the art, that our good fortune in stumbling upon a way so much more perfect cannot be sufficiently admired, when to it we are indebted for our superiority in literature above the Chinese. Their way of writing will for ever continue an unsurmountable obstruction to science; for it is so rivetted by inveterate practice, that the difficulty would not be greater to make them change their language than their letters. Hieroglyphics were a sort of writing, so miserably imperfect, as to make every improvement welcome; but as the Chinese make a tolerable shift with their own letters, they never dream of any improvement. Hence it may be pronounced with great certainty, that in China, the sciences, though still in infancy, will never arrive at maturity.
There is no appearance that writing was known in Greece so early as the time of Homer; for in none of his works is there any mention of it. This, it is true, is but negative evidence; but negative evidence must always command our assent, <174> where no positive evidence stands in opposition. If it was known, it must have been newly introduced, and used probably to record laws, religious precepts, or other short compositions.3 Cyphers, invented in Hindostan, were brought into France from Arabia about the end of the tenth century. The art of printing made a great revolution in learning. In the days of William the Conqueror, books were extremely scarce. Grace Countess of Anjou paid for a collection of homilies two hundred sheep, a quarter of wheat, another of rye, and a third of millet, beside a number of martre skins.4
Husbandry made a progress from Egypt to Greece, and from Afric to Italy. Mago, a Carthaginian general, composed twenty-eight books upon husbandry, which were translated into Latin by order of the Roman senate. From these fine and fertile countries, it made its way to colder and less kindly climates. According to that progress, agriculture must have been practised more early in France than in Britain; and yet the English, at present, make a greater figure in that art than the French, inferiority in soil and climate notwith-<175>standing. Before husbandry became an art in the northern parts of Europe, the French noblesse had deserted the country, fond of society in a town-life. Landed gentlemen in England, more rough, and delighting more in hunting and other country amusements, found leisure to practise agriculture. Skill in that art proceeded from them to their tenants, who now prosecute husbandry with success, though their landlords have generally betaken themselves to a town-life.
