[2] The oldest picture, known at present, painted in oil-colours on wood is preserved in the Imperial Gallery at Vienna. It was painted in the year 1297, by a painter named Thomas de Mutina, or de Muttersdorf, in Bohemia. Two other paintings in the same gallery are of the year 1357; one of them is by Nicholas Wurmser of Strasburg, and the other by Thierry of Prague. It appears therefore that painting in oil was known long before the epoch at which that invention is generally fixed; and that it is erroneously ascribed to Hubert van Eyck and his brother and pupil, John van Eyck, otherwise called John of Bruges, who lived about the end of the fourteenth century, and not the beginning of the fifteenth, as is commonly supposed. [There is evidence in the books of the Painters’ Company, under the date of the 11th of Edward I. (1283), that oil painting was in use at that time. See a communication from Sir Francis Palgrave given in the new edition of Carter’s Ancient Sculpture and Paintings in England, page 80.] [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.
