[3] The person who first speaks of the magnetic needle and its use in navigation, is a Provençal poet, who lived in the beginning of the thirteenth century, and who wrote a poem entitled Bible Guyot. This work is a satire, in which the author lashes with great freedom the vices of that age. Comparing the Pope to the polar star, he introduces a description of the compass, such as it appears to have been in its infancy. This invention however is claimed by the Italians, who maintain that we are indebted for it to a citizen of Amalphi, named Flavius Gioja, and in support of this assertion quote commonly the following line of Panormitanus:
Prima dedit nautis usum magnetis Amalfis.
[4] Of the use of gunpowder in Europe no certain traces occur till towards the middle of the fourteenth century. It seems pretty well proved, that artillery was known in France after the year 1345. In 1356, the city of Nuremberg purchased the first gunpowder and cannon. The same year the city of Louvain employed thirty cannon at the battle of Santfliet against the Flemings. In 1361, a fire broke out at Lubec, occasioned by the negligence of those employed in making gunpowder. In 1363, the Hans-towns used cannon for the first time, in a naval combat which they fought against the Danes. After 1367, the use of fire-arms became general throughout Italy, into which they had been introduced from Germany.
[5] The invention of printing has given rise to many researches. Meermann in his Origines Typographicæ, published in 1768, endeavours to prove that Laurence Coster of Haarlem was the inventor, about the year 1430. Most authors however agree that John Gutenberg was the inventor of moveable types, but they differ respecting the place of the invention. Some make it to be Strasburg, others Mentz, and some fix the epoch of the invention at 1440, and others at 1450.
[6] Vasari, in Vite de’ Pittori, vol. iv. p. 264, ascribes the invention of engraving on copper to a goldsmith of Florence, named Maso Finiguerra, about 1460. The oldest engravers whose names and marks are known, were Israel de Mecheln, of Bokholt, in the bishopric of Munster; Martin Schœn, who worked at Colmar in Alsace, where he died in 1486; and Michael Wolgemuth of Nuremberg, who was preceptor to the famous Albert Durer, and engraved the plates in the well-known Nuremberg Chronicle. It may be proper here to observe, that the art of engraving on wood seems to be older than the invention of printing, to which perhaps it gave rise. The names of the first engravers on wood are however not known. [In the Athenæum Journal for 1845, page 965, is given a fac-simile of a large wood-engraving, bearing the date of 1418, which was discovered at Malines in 1844, and is now preserved in the public library at Brussels.]
MEMOIR OF THE AUTHOR.
John Beckmann, Professor of Œconomy at Göttingen during a period of forty-five years, was born at Hoye, a small town in the kingdom of Hanover, in 1739. His father held the appointment of postmaster and receiver of taxes in that place, and at the same time cultivated a small farm, which appears to have inspired his son with a taste for agricultural pursuits. The superintendence of his education devolved principally on his mother, a woman of great prudence and strength of mind, who was left a widow when young Beckmann was scarcely seven years old. In a lonely house, amid examples of industry and daily labour, he passed his youth in the perusal of works, which, although of a common-place description, were not without their use, as they led him to contract a methodical habit of mind, and afforded considerable information on various subjects, which in the sequel greatly assisted him in the pursuits to which he owed his celebrity. He himself relates that, when quite a boy, he was in the habit of making extracts of all the striking passages he met with in the course of his reading, by which means he acquired a ready use of the pen. The insufficient circumstances of his family prevented his education being cultivated in the schools till nearly fifteen; at which age he was sent to the Gymnasium of Stade, then under the direction of Gehlen, where in a short time he highly distinguished himself in classical literature. Intended for the clerical profession, he entered the university of Göttingen in 1759, for the purpose of completing his theological studies; but whether the advice of Hollmann (afterwards his father-in-law), with whom he had formed a close intimacy, produced a change in his plans, or that the mathematical instructions of Professors Kaestner and Mayer were more congenial to his mind than divinity, he abandoned the career marked out for him, and devoted himself to the natural sciences and their application, as well as to mathematics; whilst he cultivated philology with such zeal, that he ultimately made himself master of ten different languages. In order to gain greater proficiency in these pursuits, he made a journey in 1762 to the Netherlands, but returned to Hoye in the following year, in consequence of the serious indisposition of his mother, who dying shortly afterwards, left him destitute of guidance, and in the greatest anxiety respecting his future prospects. At this juncture Büsching advised him to travel to St. Petersburg, where, upon the strong recommendations with which he was provided, he was speedily appointed to the chair of Natural Philosophy. Shortly after, Büsching, quitting the institution, returned to Germany, and dissensions having arisen among the directors, Beckmann likewise resigned his office. He then proceeded to Sweden, with the view of acquiring a detailed knowledge of the working of the mines in that country; making his principal sojourn at Upsal, where he became acquainted with Linnæus, and enjoyed the friendship and hospitality, as well as the instructions, of that eminent naturalist[7]. Leaving Sweden, he directed his course to Denmark, visiting Copenhagen and other towns, where he examined the various museums, libraries and manufacturing establishments. On arriving at Altona, he found there his friend Büsching, who recommended him to Münchhausen, curator of the Academy of Göttingen. After paying a visit to his brother at Marburgh, he proceeded to Hanover; and being approved of by Struve, then president of Göttingen under Münchhausen, he was appointed, in 1766, Professor Extraordinary of Philosophy to that university, of which he eventually became one of the brightest ornaments.
His lectures upon œconomy had the recommendation of novelty, and produced so much applause, that in 1770 he was made ordinary professor of that science. They were attended by the flower of the studious youth of all countries, Göttingen being at that period one of the most popular universities in Europe; and many even of the distinguished statesmen and public functionaries of Germany did not disdain to be ranked among his auditors. He was in the habit of accompanying them himself into the workshops, to give them a practical knowledge of the different processes and handicrafts of which he had explained the theory. Once a week, also, he held a Practicum Camerale, a scientific meeting, at which he explained subjects of œconomy, administration, and finance, illustrating them by readings from a great variety of sources. He composed, to serve as a guide in this course of instruction, treatises on rural œconomy, policy, finance, commerce, and other departments of knowledge; which, though since carried to a higher degree of perfection, owed to Beckmann their first systematic form. He never entirely relinquished these public lectures, but insensibly his private studies took a direction altogether historical, the motives for which it may not be uninteresting to point out.
It is indispensably requisite at Göttingen that every professor should be able to give account of the progress and existing state of the science to which he is appointed. Any one, who two years after the publication of a work of importance in his department should not have read and analysed it, with a view of enriching his own observations, would not be regarded as a worthy successor to the chair of Haller, of Mosheim, of Gessner and Michaelis. Beckmann, who had studied at Göttingen at a time when the example of these great men dictated the law and gave the tone to the University, and perhaps to the literature of Europe, was determined to keep pace with the spirit of the age, and not to remain ignorant of the great advances then making throughout Europe, in the numerous sciences which furnished the subjects of his practical investigations. But this was a task of no slight magnitude: and indeed when the immense additions to so many different sciences are considered, can it be wondered at, that, notwithstanding his utmost zeal and application, he found it impossible to read up all the important works which had appeared since 1770, in chemistry, physics, natural history and mathematics? Despairing of success in so Herculean an undertaking, he began to entertain feelings of aversion towards what he deemed the innovations, which were then changing the face and enlarging the scope of science. But his course of lectures, turning principally on practical matters, was not materially affected; he was, however, so fearful of falling under the imputation of being behind the progress of the age, that he devoted his mind, peculiarly fitted for this kind of study, almost exclusively to the history of arts and trades; employing in the illustration of his subjects, the materials to which he had access in the very extensive library belonging to the university; and it is to his consequent labours and researches that we owe the “History of Inventions and Discoveries.” In this work, Beckmann traces their first germs from the remotest periods of antiquity, and following their gradual development, exhibits the latest improvements among civilized nations with almost unequalled acumen and ability. It abounds with invaluable materials respecting the general history of the origin and progress of the mechanic arts, which are so important a branch in civilization; and what must give it an additional value in the eyes of all who are unwilling to place reliance on assertions unsupported by authority, or may be anxious to investigate the subject more deeply, the most scrupulous references to original authorities accompany each article. Among the numerous other works of merit for which we are indebted to the literary industry of Beckmann, are, “A History and Analysis of early Voyages and Travels,” a highly interesting collection, which occupied the last years of his life, and was left unfinished at the eighth number; elaborate editions of “De Mirabilibus Auscultationibus,” attributed to Aristotle, 1786; “Antigoni Carystii Historiæ Mirabiles,” 1791; and “Marbodi Liber de Gemmis,” 1799; publications which required the rare combination of physical knowledge with philological learning.
