when they suppose that the figure of a cock was first made choice of for vanes in the fourteenth century, under the reign of Edward III., in order to ridicule the French, with whom they were then at war; and that the custom of cock-throwing, that is to say, of throwing sticks at a cock exposed with his wings tied, as then practised, took its rise at the same time. In France, in the twelfth century, none but noblemen were allowed to have vanes on their houses; nay, at one time this was the privilege of those who, at the storming of a town, first planted their standards on the ramparts. These vanes were painted with the knights' arms, or the arms were cut out in them, and in that case they were called panonceaux1. Flags or vanes on ships occur very early, but they are always mentioned on account of their use in making signals. They were of various forms and colours; were sometimes drawn up, and sometimes taken down; placed sometimes on the right and sometimes on the left side of the ship, and were changed in various other ways, directions for which may be seen in the Tactics of the emperor Leo. They were named vexilla, flammulæ, also flammula and banda, and the last two appellations occur in the works of the younger Greek writers 2. But though the oldest writers on the art of naval warfare, such as Vegetius, recommend a knowledge of the winds, I have not yet met with any certain account of apparatus for determining the direction of them on board a ship. Before the discovery of the magnetic needle, such accuracy as is necessary at present would have been superfluous; yet naval commanders must long before have had some means of distinguishing at least the twelve winds then defined, though no traces of them are to be found in the works which have been accidentally preserved to us. Scheffer, who, as is well-known, collected from the works of the ancients all the terms of art applicable to navigation, thinks that the band, tania, affixed to a pole at the stern of the ship, did not serve so much for an ornament as to indicate the course of the wind. He is, however, able to produce no other authority for this opinion than a passage in one of Cicero's letters, which has been changed and amended, till it at length seems to say that Cicero had resolved to embark, because the vanes had announced a favourable wind1. 1 Dictionnaire à Trevoux, 1704, fol. article Girouette. 2 Hirtius de Bello Alexand. cap. 45.

I must acknowledge that at present I can produce no older information in regard to vanes used on board ship, to indicate the course of the wind, than of the eleventh century, taken from the life of Emma, the consort of Canute the Great, king of Denmark, Norway and England, the author of which was an eye-witness of what he relates. Describing the magnificent Norman fleet sent to England in the year 1013, he says that birds, which turned round with the wind, were placed on the top of the masts2. At that time, therefore, instead of the flags used at present, a vane, shaped like a bird, was placed at the summit of the mast; perhaps also the figure of a cock, as the emblem of vigilance, but in this case not of clerical vigilance. In the cathedral of Bayeux, in France, is a piece of tapestry, representing the actions of William the Conqueror, executed with the needle, either by his consort or under her direction, in which vanes are seen at the top of the masts in many of the ships3. [Anemoscopes, or instruments for showing the direction of the wind, are now in constant use in meteorological establishments; the indications are made upon dials, and the apparatus does not differ in principle from that described by Beckmann. Anemometers, or instruments for measuring the power or force of the wind, have also been contrived of various kinds. The first was invented by Wolf. In this the wind acted upon four sails somewhat resembling those of a windmill, the motion being communicated by cog-wheels to a lever loaded with a weight. When the wind acted upon the sails, the bar rose, this motion continuing until the increased leverage of the weight counterpoised the moving power of the wind. Others on a different principle have been made by Lind, Regnier, Martin, and a very beautiful instrument for this purpose, constructed by Mr. Dent, may be seen at Lloyd's room in the Royal Exchange.] 2 The Encomium Emmæ is printed in Du Chesne, Historiæ Normannor Scriptor.

THE astonishing extensibility of gold, a property in which it far surpasses all other metals, induced mankind, at an early period, to attempt beating it into thin plates, as the value of it led them to the art of covering or gilding things of every kind with leaves of it. It is proved by Herodotus, that the Egyptians were accustomed to gild wood and metals'; and gilding is frequently mentioned in the books of the Old Testament. The gold plates, however, used for this purpose, 1 Herodot. lib. ii. 63. See Winkelmann Hist. de l'Art. -Caylus, Recueil d'Antiquités, i. p. 193. Gori seems to have had in his possession two Egyptian gilt figures. See Mus. Etr. t. i. p. 51. 2 In the books of the Old Testament gilding and gold plates are clearly mentioned. Moses caused several parts of the sanctuary to be overlaid with gold. 1st. The ark of shittim wood was covered with gold both on the outside and inside, Exodus, chap. xxv. ver. 11; also the staves, ver. 13. 2nd. The wooden table with its staves, ver. 23 and 28. 3rd. The altar of burnt incense, chap. xxx. ver. 3. 4th. The boards which formed the sides of the tabernacle, chap. xxvi. ver. 29. Solomon caused various parts of the temple to be overlaid with gold. 1st. The whole inside of the house, 1 Kings, chap. vi. ver. 21 and 22. 2nd. The altar of burnt incense, ver. 20 and 22. 3rd. The wooden cherubim above seventeen feet in height, ver. 28. 4th. The floor, ver. 30. 5th. The doors of the oracle, on which were carved cherubims, palm-trees and open flowers, ver. 32 and 35, so that the gold accurately exhibited the figures of the carved work. Now the question is, whether all these were gilt, or covered, or overlaid with gold plates. But when the passages are compared with each other, I am inclined to think that gilding is denoted. "The Hebrews probably brought the art of gilding with them from Egypt, where it seems to have been very old, as gilding is found not only on mummies, the antiquity of which indeed is uncertain; but, if I am not mistaken, in the oldest temples, on images. It appears also, that in the time of Moses the Hebrews understood the art both of gilding and of as may be readily conceived, were not so thin as those made at present; and for this reason, the gilding on statues, which have lain many centuries in the earth, appears to be still entire. Winkelmann says', that among the ruins of two apartments in the imperial palace, on the palatine hill, in the Villa Farnese, the gold ornaments were found to be as fresh as if they had been newly applied, though these apartments, in consequence of being buried under the earth, were exceedingly damp. The circular bands of sky-blue, with small figures in gold, could not be seen without admiration. The gilding also is still preserved in the ruins of Persepolis. But, in the time of Pliny, the art of gold-beating was carried so far at Rome, that an ounce of gold could be beat into seven hundred and fifty leaves and more, each four square inches in size. I shall not compare this result with what the art can do at present, because the account of Pliny is not the most accurate, and because the conversion of the old measures into the modern standard is always attended with uncertainty. Buonarotti, however, who made some researches on this subjects, is of opinion that the gold used at Rome for fire-gilding in his time, that is, at the end of the seventeenth century, was beat six times as thin; and that the gold employed for gilding wood and other things, without the application of fire, was twenty-two times as thin as the gold leaf made at Rome in the time of Pliny. But this Italian author, as appears to me, has, through too great precipitation, translated the words "septingenæ et quinquagenæ bracteæ" fifty and seventy. Gold, however, at that time, was beat so thin at Rome, that Lucretius compares it to a spider's web, and Martial to a vapour4. I have, however, not yet met with any information in regard to the method in which the ancient artists beat the gold, or the instruments and apparatus they employed for that purpose. But the German monk Theophilus, whose real name seems to have been Rüger, and who, as Lessing thinks, lived overlaying with plates of gold, and expressed both by the general term ".צפה 1 Page 534. 2 Lib. xxxiii. 3. The thicker gold-leaf was called, at that time, bractea Prænestina; the thinner, bractea quæstoria. 3 Osservazioni Istoriche sopra alcuni Medaglioni Antichi. In Roma, 1698, fol. p. 370. 4 Lucret. iv. 730.- Martial. viii. 33. in the ninth, but, according to Morelli, in the twelfth century, describes the process nearly as it is at present1. The gold, at that time, was beat between parchment, in the same manner as is still practised; and the artists knew how to prevent the gold from adhering to the parchment, by covering it over with burnt ochre reduced to a very fine powder, and then rubbing it smooth with a tooth. With the like view, our gold-beaters rub over with a fine bolus the thin paper used for making the books into which they put their gold leaf, in order to preserve it. But the flatting-mills, between the steel rollers of which cast and hammered ingots of gold are at present reduced to thin leaves, seem not to have been then known, at least this monk makes no mention of them. Lessing, to whom we are indebted for this curious fragment of Theophilus, is of opinion that each artist at that time was obliged to beat the gold leaf which he used, because gold-beating was not then a distinct branch of business. This I will not controvert; but it is no proof of it, that the monk taught the art to his brethren; for in convents the clergy endeavoured to make everything they used, in order that they might purchase as little as possible. During the progress of the art, it being found that parchment was too thick and hard for the above purpose, workmen endeavoured to procure some finer substance, and at length discovered that the skin of an unborn calf was the most convenient. By means of this improvement, gold leaf was made much thinner than it had ever been before possible; but the art was brought to still greater perfection by employing that fine pellicle which is detached from the gut of an ox or a cow. Lancellotti, who wrote in the first half of the seventeenth century, says that this invention was made by the German gold-beaters, when, in consequence of the war, they were not able to obtain from Flanders the skins of unborn calves. I have often heard that the preparation of this pellicle, which the French call baudruche and the Dutch liezen, and which is so thin that two of them must be pasted together, is a secret, and that the best is obtained from England. But in the year 1785, when I paid a visit to a very ingenious goldbeater at Hamburg, he assured me that he prepared this 1 Lessing zur Geschichte und Litteratur, iv. p. 309. 2 L'oggidi overo gl'ingegni non inferiori à passati.
