For the long and complicated bibliography of the Nights reference can be made to Victor Chauvin's Bibliographie des Ouvrages Arabes, pt. iv. to vii. (Liege, 1900-o3). This is a thesaurus of the whole subject. Still worth reference is J.Rfostrup's Studier over Tusind og en Nat (Copenhagen, 1891). Of this there is an abbreviated French translation by E. Galtier in Memoires de l'Institut Francais du Caire, vol. xxvii., and a German trans lation by 0. Rescher (Stuttgart, 1925) with valuable additions bringing it to that date. English is fortunate in its direct trans lations from the Arabic ; all, however, from the printed texts of the modern Egyptian Recension. In 1838, Henry Torrens pub lished a very remarkable version (Calcutta and London) of the first 5o Nights, giving the feeling of the original in prose and verse better than almost any other. Lane's incomplete version (3 vol. London, 1839-41) is from the Bulaq edition and shows his deep knowledge of Cairene Arabic ; the commentary is very valuable. The version by John Payne (Villon Society, 9 vol. 1882-84) from the Calcutta edition is a faithful and complete rendering into rather sophisticated translator's English. The prose part of Burton's version (Benares, io vol., 1885) is largely dependent upon Payne, but treated after Burton's fashion; the verse is his own. An excellent and complete German translation by Enno Littmann of the University of Tübingen has appeared at Leipzig; it is from the Calcutta text with additions, and the sixth volume, published in 1928, contains a valuable study (pp. 681 771) of the translating, origin, contents and history of the Nights. The French version of J. C. Mardrus (Paris, 1899 ff.), professedly from the Bulaq edition, is unfaithful to a large degree and repre sents no known Arabic text; the same holds of the various versions derived from it in English, Spanish and Polish. (D. B. M.) THRACE, a name applied at various periods to areas of dif ferent extent. Since 1923 Thrace has been divided between Greece (Western Thrace) and Turkey (Eastern Thrace). The boundaries of the Roman province of Thrace were—north, the Haemus; east, the Euxine sea ; south, the Propontis, the Hellespont and the Ae gean; and west, the Nestus. The distinguishing features of the country were the chain of Rhodope (Despotodagh) and the river Hebrus (Maritza). The former separates from the Haemus at right angles, and runs southward, parallel to the Nestus, until it approaches the sea, when it takes an easterly direction. Several of the summits of this chain are over 7,000ft. in height. The Hebrus, with its tributaries, drains almost the whole of Thrace. It starts from near the point of junction of Haemus and Rhodope, and takes an easterly direction, but at Hadrianopolis it makes a sharp bend towards the south, and enters the sea nearly opposite the is land of Samothrace. The greater part of the country is hilly and irregular; besides Rhodope two other tolerably definite chains in tersect it, one of which descends from Haemus to Adrianople, while the other follows the coast of the Euxine at no great distance inland. One district in the extreme north-west of Thrace lay be yond the watershed separating the streams that flow into the Ae gean from those that reach the Danube : this was the territory of Sardica, the modern Sofia. In the later Roman period two main lines of road passed through the country. One of these skirted the southern coast, being a continuation of the Via Egnatia, from Dyrrhachium to Thessalonica, connecting the Adriatic and the Aegean ; it became of the first importance after the foundation of Constantinople. The other followed a north-westerly course through the interior, from Constantinople by Hadrianopolis and Philippopolis to the Haemus, and thence through Moesia in the direction of Pannonia, taking the route by which the railway now runs from Constantinople to Belgrade.
The climate of Thrace was regarded by the Greeks as severe, and that country was spoken of as the home of the north wind, Boreas. The coast of the Euxine was feared by sailors, as the har bours were few and the sea tempestuous ; but on the southern shore we find the Greek colonies of Abdera and Mesambria on the Aegean, Perinthus on the Propontis, and, the most famous of all, Byzantium (q.v.). Colonies were also planted in the Thracian Chersonese, between the Hellespont and the Bay of Melas ; among its cities were Sestos and Callipolis (Gallipoli). In order to pre vent the incursions of the Thracians, a wall was built across its isthmus, which was less than 5m. in breadth.
