DIERX, LÉON (1838- ), French poet, was born in the island of Réunion in 1838. He came to Paris to study at the Central School of Arts and Manufactures, and subsequently settled there, taking up a post in the education office. He became a disciple of Leconte de Lisle and one of the most distinguished of the Parnassians. In the death of Stéphane Mallarmé in 1898 he was acclaimed “prince of poets” by “les jeunes.” His works include: Poèmes et poésies (1864); Lèvres closes (1867); Paroles d’un vaincu (1871); La Rencontre, a dramatic scene (1875) and Les Amants (1879). His Poésies complètes (1872) were crowned by the French Academy. A complete edition of his works was published in 2 vols., 1894-1896.
DIES, CHRISTOPH ALBERT (1755-1822), German painter, was born at Hanover, and learned the rudiments of art in his native place. For one year he studied in the academy of Dusseldorf, and then he started at the age of twenty with thirty ducats in his pocket for Rome. There he lived a frugal life till 1796. Copying pictures, chiefly by Salvator Rosa, for a livelihood, his taste led him to draw and paint from nature in Tivoli, Albano and other picturesque places in the vicinity of Rome. Naples, the birthplace of his favourite master, he visited more than once for the same reasons. In this way he became a bold executant in water-colours and in oil, though he failed to acquire any originality of his own. Lord Bristol, who encouraged him as a copyist, predicted that he would be a second Salvator Rosa. But Dies was not of the wood which makes original artists. Besides other disqualifications, he had necessities which forced him to give up the great career of an independent painter. David, then composing his Horatii at Rome, wished to take him to Paris. But Dies had reasons for not accepting the offer. He was courting a young Roman whom he subsequently married. Meanwhile he had made the acquaintance of Volpato, for whom he executed numerous drawings, and this no doubt suggested the plan, which he afterwards carried out, of publishing, in partnership with Méchan, Reinhardt and Frauenholz, the series of plates known as the Collection de vues pittoresques de l’Italie, published in seventy-two sheets at Nuremberg in 1799. With so many irons in the fire Dies naturally lost the power of concentration. Other causes combined to affect his talent. In 1787 he swallowed by mistake three-quarters of an ounce of sugar of lead. His recovery from this poison was slow and incomplete. He settled at Vienna, and lived there on the produce of his brush as a landscape painter, and on that of his pencil or graver as a draughtsman and etcher. But instead of getting better, his condition became worse, and he even lost the use of one of his hands. In this condition he turned from painting to music, and spent his leisure hours in the pleasures of authorship. He did not long survive, dying at Vienna in 1822, after long years of chronic suffering. From two pictures now in the Belvedere gallery, and from numerous engraved drawings from the neighbourhood of Tivoli, we gather that Dies was never destined to rise above a respectable mediocrity. He followed Salvator Rosa’s example in imitating the manner of Claude Lorraine. But Salvator adapted the style of Claude, whilst Dies did no more than copy it.
DIEST, a small town in the province of Brabant, Belgium, situated on the Demer at its junction with the Bever. Pop. (1904) 8383. It lies about half-way between Hasselt and Louvain, and is still one of the five fortified places in Belgium. It contains many breweries, and is famous for the excellence of its beer.
DIESTERWEG, FRIEDRICH ADOLF WILHELM (1790-1866), German educationist, was born at Siegen on the 29th of October 1790. Educated at Herborn and Tübingen universities, he took to the profession of teaching in 1811. In 1820 he was appointed director of the new school at Mörs, where he put in practice the methods of Pestalozzi. In 1832 he was summoned to Berlin to direct the new state-schools seminary in that city. Here he proved himself a strong supporter of unsectarian religious teaching. In 1846 he established the Pestalozzi institution at Pankow, and the Pestalozzi societies for the support of teachers’ widows and orphans. In 1850 he retired on a pension, but continued vigorously to advocate his educational views. In 1858 he was elected to the chamber of deputies as member for the city of Berlin, and voted with the Liberal opposition. He died in Berlin on the 7th of July 1866. Diesterweg was a voluminous writer on educational subjects, and was the author of various school text-books.
DIET, a term used in two senses, (1) food or the regulation of feeding (see [Dietary] and [Dietetics]), (2) an assembly or council (Fr. diète; It. dieta; Low Lat. diaeta; Ger. Tag). We are here concerned only with this second sense. In modern usage, though in Scotland the term is still sometimes applied to any assembly or session, it is practically confined to the sense of an assembly of estates or of national or federal representatives. The origin of the word in this connotation is somewhat complicated. It is undoubtedly ultimately derived from the Greek δίαιτα (Lat. diaeta), which meant “mode of life” and thence “prescribed mode of life,” the English “diet” or “regimen.” This was connected with the verb διαιτᾶν, in the sense of “to rule,” “to regulate”; compare the office of διαιτητής at Athens, and dieteta, “umpire,” in Late Latin. In both Greek and Latin, too, the word meant “a room,” from which the transition to “a place of assembly” and so to “an assembly” would be easy. In the latter sense the word, however, actually occurs only in Low Latin, Du Cange (Glossarium, s.v.) deriving it from the late sense of “meal” or “feast,” the Germans being accustomed to combine their political assemblies with feasting. It is clear, too, that the word diaeta early became confused with Lat. dies, “day” (Ger. Tag), “especially a set day, a day appointed for public business; whence, by extension, meeting for business, an assembly” (Skeat). Instances of this confusion are given by Du Cange, e.g. diaeta for dieta, “a day’s journey” (also an obsolete sense of “diet” in English), and dieta for “the ordinary course of the church,” i.e. “the daily office,” which suggests the original sense of diaeta as “a prescribed mode of life.”
The word “diet” is now used in English for the Reichstag, “imperial diet” of the old Holy Roman Empire; for the Bundestag, “federal diet,” of the former Germanic confederation; sometimes for the Reichstag of the modern German empire; for the Landtage, “territorial diets” of the constituent states of the German and Austrian empires; as well as for the former or existing federal or national assemblies of Switzerland, Hungary, Poland, &c. Although, however, the word is still sometimes used of all the above, the tendency is to confine it, so far as contemporary assemblies are concerned, to those of subordinate importance. Thus “parliament” is often used of the German Reichstag or of the Russian Landtag, while the Landtag, e.g. of Styria, would always be rendered “diet.” In what follows we confine ourselves to the diet of the Holy Roman Empire and its relation to its successors in modern Germany.
