LEVERTIN, OSCAR IVAN (1862-1906), Swedish poet and man of letters, was born of Jewish parents at Norrköping on the 17th of July 1862. He received his doctorate in letters at Upsala in 1887, and was subsequently docent at Upsala, and later professor of literature at Stockholm. Enforced sojourns in southern Europe on account of health familiarized him with foreign languages. He began by being an extreme follower of the naturalist school, but on his return in 1890 from a two years’ residence in Davos he wrote, in collaboration with the poet C. G. Verner von Heidenstam (b. 1859), a novel, Pepitas bröllop (1890), which was a direct attack on naturalism. His later volumes of short stories, Rococonoveller and Sista noveller, are fine examples of modern Swedish fiction. The lyrical beauty of his poems, Legender och visor (1891), placed him at the head of the romantic reaction in Sweden. In his poems entitled Nya Dikter (1894) he drew his material partly from medieval sources, and a third volume of poetry in 1902 sustained his reputation. His last poetical work (1905) was Kung Salomo och Morolf, poems founded on an eastern legend. As a critic he first attracted attention by his books on the Gustavian age of Swedish letters: Teater och drama under Gustaf III. (1889), &c. He was an active collaborator in the review Ord och Bild. He died in 1906, at a time when he was engaged on his Linné, posthumously published, a fragment of a great work on Linnaeus.

LEVI, HERMANN (1839-1900), German orchestral conductor, was born at Giessen on the 7th of November 1839, and was the son of a Jewish rabbi. He was educated at Giessen and Mannheim, and came under Vincenz Lachner’s notice. From 1855 to 1858 Levi studied at the Leipzig conservatorium, and after a series of travels which took him to Paris, he obtained his first post as music director at Saarbrücken, which post he exchanged for that at Mannheim in 1861. From 1862 to 1864 he was chief conductor of the German opera in Rotterdam, then till 1872 at Carlsruhe, when he went to Munich, a post he held until 1896, when ill-health compelled him to resign. Levi’s name is indissolubly connected with the increased public appreciation of Wagner’s music. He conducted the first performance of Parsifal at Bayreuth in 1882, and was connected with the musical life of that place during the remainder of his career. He visited London in 1895.

LEVI, LEONE (1821-1888), English jurist and statistician, was born of Jewish parents on the 6th of June 1821, at Ancona, Italy. After receiving an early training in a business house in his native town, he went to Liverpool in 1844, became naturalized, and changing his faith, joined the Presbyterian church. Perceiving the necessity, in view of the unsystematic condition of the English law on the subject, for the establishment of chambers and tribunals of commerce in England, he warmly advocated their institution in numerous pamphlets; and as a result of his labours the Liverpool Chamber of Commerce, of which Levi was made secretary, was founded in 1849. In 1850 Levi published his Commercial Law of the World, being an exhaustive and comparative treatise upon the laws and codes of mercantile countries. Appointed in 1852 to the chair of commercial law in King’s College, London, he proved himself a highly competent and popular instructor, and his evening classes were a most successful innovation. He was called to the bar at Lincoln’s Inn in 1859, and received from the university of Tübingen the degree of doctor of political science. His chief work—History of British Commerce and of the Economic Progress of the British Nation, 1763-1870, is perhaps a rather too partisan account of British economic development, being a eulogy upon the blessings of Free Trade, but its value as a work of reference cannot be gainsaid. Among his other works are: Work and Pay; Wages and Earnings of the Working Classes; International Law, with Materials for a Code. He died on the 7th of May 1888.

LEVIATHAN, the Hebrew name (livyāthān), occurring in the poetical books of the Bible, of a gigantic animal, apparently the sea or water equivalent of behemoth (q.v.), the king of the animals of the dry land. In Job xli. 15 it would seem to represent the crocodile, in Isaiah xxvii. 1 it is a crooked and piercing serpent, the dragon of the sea; cf. Psalms civ. 26. The etymology of the word is uncertain, but it has been taken to be connected with a root meaning “to twist.” Apart from its scriptural usage, the word is applied to any gigantic marine animal such as the whale, and hence, figuratively, of very large ships, and also of persons of outstanding strength, power, wealth or influence. Hobbes adopted the name as the title of his principal work, applying it to “the multitude so united in one person ... called a commonwealth.... This is the generation of that Leviathan, or rather ... of that mortal God, to which we owe under the immortal God, our peace and defence.”

LEVIRATE (Lat. levir, a husband’s brother), a custom, sometimes even a law, compelling a dead man’s brother to marry his widow. It seems to have been widespread in primitive times, and is common to-day. Of the origin and primitive purpose of the levirate marriage various explanations have been put forward:—
