Dictys Of Crete, the reputed author of a history of the Trojan war. The MS., written in Phoenician characters, but in the Greek language, is said to have been found in the author's tomb at Cnossus in the reign of Nero. A Latin version in six books has come down to us, but the work is commonly regarded as a forgery. Dictys is said to have followed Ido-meneus, king of Crete, to the siege of Troy, and some ancient grammarians have imagined that Homer drew materials for the Iliad and Odyssey from his history. It was the chief basis of the mediaeval literature relating to the siege of Troy, and was among the first books printed in the loth century.
Didymium (Gr. twin), a metal discovered in 1841 by Mosander in the mineral cerite, and named for its resemblance to the metal lanthanum, which occurs in the same mineral, and for the persistence with which its salts remain combined with those of this metal. The rose color of the salts of lanthanum is probably due to the presence of didymium. But neither of the two metals, nor the cerium with which they occur, possesses any special interest, and the complete quantitative separation of the metals is even yet attended with great difficulty.
Didymus, an Alexandrian grammarian and critic, born about 64 B. 0. He was noted for his industry and the copiousness of his writings, in consequence of which he received the nicknames of or brazen-bowelled, and or forgetter of books. The number of his works is stated by Athenaeus at 3,500, and by Seneca at 4,000.
Diedenhofen (Fr. Thionville), a fortified town of Germany, in Lorraine, situated on the Moselle, and on the railway from Metz to Luxemburg, about 15 m. N. of Metz ; pop. in 1871, 7,155. It has a gymnasium, a botanic garden, and manufactories of hosiery, woollen cloths, candles, leather, liqueurs, and spirits. The Carlovingian kings of France frequently resided here; subsequently the town belonged in succession to the counts of Luxemburg, to Burgundy, Austria, and Spain. In 1G43, when it surrendered to the prince of Conde, it was annexed to France. In 1870 it suffered considerably from bombardment by the German troops, to whom the French garrison, consisting of 120 officers and 4,000 men, surrendered on Nov. 24. By the peace of May 10, 1871, it was ceded to Germany. The town is well built, and the fortifications constitute a fortress of the third class.
Diego Enriquez Do Castillo, a Spanish chronicler of the 15th century, born at Segovia. His annals of the reign of Henry IV. of Castile, from 1454 to 1474, were published by Jose Miguel de Flores (Madrid, 1787). He also composed a poem relating to the death of Alfonso V. of Aragon, published by Ochoa (Paris, 1844), in the same volume with the inedited poems of the marquis of Santillana. Castillo is said to have fallen into the hands of Henry's younger brother Alfonso, the pretender to the throne, after the battle of Olmedo; but little is known about his career, except that he was employed in important missions.
