KNAVE (O.E. cnafa, cognate with Ger. Knabe, boy), originally a male child, a boy (Chaucer, Canterbury Tales: “Clerk’s Tale,” I. 388). Like Lat. puer, the word was early used as a name for any boy or lad employed as a servant, and so of male servants in general (Chaucer: “Pardoner’s Tale,” 1. 204). The current use of the word for a man who is dishonest and crafty, a rogue, was however an early usage, and is found in Layamon (c. 1205). In playing-cards the lowest court card of each suit, the “jack,” representing a medieval servant, is called the “knave.” (See also [Valet].)

KNEBEL, KARL LUDWIG VON (1744-1834), German poet and translator, was born at the castle of Wallerstein in Franconia on the 30th of November 1744. After having studied law for a short while at Halle, he entered the regiment of the crown prince of Prussia in Potsdam and was attached to it as officer for ten years. Disappointed in his military career, owing to the slowness of promotion, he retired in 1774, and accepting the post of tutor to Prince Konstantin of Weimar, accompanied him and his elder brother, the hereditary prince, on a tour to Paris. On this journey he visited Goethe in Frankfort-on-Main, and introduced him to the hereditary prince, Charles Augustus. This meeting is memorable as being the immediate cause of Goethe’s later intimate connexion with the Weimar court. After Knebel’s return and the premature death of his pupil he was pensioned, receiving the rank of major. In 1798 he married the singer Luise von Rudorf, and retired to Ilmenau; but in 1805 he removed to Jena, where he lived until his death on the 23rd of February 1834. Knebel’s Sammlung kleiner Gedichte (1815), issued anonymously, and Distichen (1827) contain many graceful sonnets, but it is as a translator that he is best known. His translation of the elegies of Propertius, Elegien des Properz (1798), and that of Lucretius’ De rerum natura (2 vols., 1831) are deservedly praised. Since their first acquaintance Knebel and Goethe were intimate friends, and not the least interesting of Knebel’s writings is his correspondence with the eminent poet, Briefwechsel mit Goethe (ed. G. E. Guhrauer, 2 vols., 1851).

Knebel’s Literarischer Nachlass und Briefwechsel was edited by K. A. Varnhagen von Ense and T. Mundt in 3 vols. (1835; 2nd ed., 1840). See Hugo von Knebel-Döberitz, Karl Ludwig von Knebel (1890).

KNEE (O.E. cnéow, a word common to Indo-European languages, cf. Ger. Knie, Fr. genou, Span, hinojo, Lat. genu, Gr. γόνυ, Sansk. janu), in human anatomy, the articulation of the upper and lower parts of the leg, the joint between the femur and the tibia (see [Joints]). The word is also used of articulation resembling the knee-joint in shape or position in other animals; it thus is applied to the carpal articulation of the fore leg of a horse, answering to the ankle in man, or to the tarsal articulation or heel of a bird’s foot.

KNELLER, SIR GODFREY (1648-1723), a portrait painter whose celebrity belongs chiefly to England, was born in Lübeck in the duchy of Holstein, of an ancient family, on the 8th of August 1648. He was at first intended for the army, and was sent to Leyden to learn mathematics and fortification. Showing, however, a marked preference for the fine arts, he studied in the school of Rembrandt, and under Ferdinand Bol in Amsterdam. In 1672 he removed to Italy, directing his chief attention to Titian and the Caracci; Carlo Maratta gave him some guidance and encouragement. In Rome, and more especially in Venice, Kneller earned considerable reputation by historical paintings as well as portraits. He next went to Hamburg, painting with still increasing success. In 1674 he came to England at the invitation of the duke of Monmouth, was introduced to Charles II., and painted that sovereign, much to his satisfaction, several times. Charles also sent him to Paris, to take the portrait of Louis XIV. When Sir Peter Lely died in 1680, Kneller, who produced in England little or nothing in the historical department, remained without a rival in the ranks of portrait painting; there was no native-born competition worth speaking of. Charles appointed him court painter; and he continued to hold the same post into the days of George I. Under William III. (1692) he was made a knight, under George I. (1715) a baronet, and by order of the emperor Leopold I. a knight of the Roman Empire. Not only his court favour but his general fame likewise was large: he was lauded by Dryden, Addison, Steele, Prior, Tickell and Pope. Kneller’s gains also were very considerable; aided by habits of frugality which approached stinginess, he left property yielding an annual income of £2000. His industry was maintained till the last. His studio had at first been in Covent Garden, but in his closing years he lived in Kneller Hall, Twickenham. He died of fever, the date being generally given as the 7th of November 1723, though some accounts say 1726. He was buried in Twickenham church, and has a monument in Westminster Abbey. An elder brother, John Zachary Kneller, an ornamental painter, had accompanied Godfrey to England, and had died in 1702. The style of Sir Godfrey Kneller as a portrait painter represented the decline of that art as practised by Vandyck; Lely marks the first grade of descent, and Kneller the second. His works have much freedom, and are well drawn and coloured; but they are mostly slight in manner, and to a great extent monotonous, this arising partly from the habit which he had of lengthening the oval of all his heads. The colouring may be called brilliant rather than true. He indulged much in the common-places of allegory; and, though he had a quality of dignified elegance not unallied with simplicity, genuine simple nature is seldom to be traced in his works. His fame has greatly declined, and could not but do so after the advent of Reynolds. Among Kneller’s principal paintings are the “Forty-three Celebrities of the Kit-Cat Club,” and the “Ten Beauties of the Court of William III.,” now at Hampton Court; these were painted by order of the queen; they match, but match unequally, the “Beauties of the Court of Charles II.,” painted by Lely. He executed altogether the likenesses of ten sovereigns, and fourteen of his works appear in the National Portrait Gallery. It is said that Kneller’s own favourite performance was the portrait of the “Converted Chinese” in Windsor Castle. His later works are confined almost entirely to England, not more than two or three specimens having gone abroad after he had settled here.
