ISSERLEIN, ISRAEL (d. 1460), German Talmudist. His fame attracted many students to Neustadt, and his profound learning did much to revive the study of the original Rabbinic authorities. After the publication of the Code of Joseph Qaro (q.v.) the decisions of Isserlein in legal matters were added in notes to that code by Moses Isserles. His chief works were Terumath ha-Deshēn (354 decisions) and Peasqim u-kethaḥim (267 decisions) largely on points of the marriage law.
ISSERLES, MOSES BEN ISRAEL (c. 1520-1572), known as Remā, was born at Cracow and died there in 1572. He wrote commentaries on the Zohar, the “Bible of the Kabbalists,” but is best known as the critic and expander of the Shulḥan Aruch of Joseph Qaro (Caro)(q.v.). His chief halakhic (legal) works were Darke Moshē and Mappāh. Qaro, a Sephardic (Spanish) Jew, in his Code neglected Ashkenazic (German) customs. These deficiencies Isserles supplied, and the notes of Remā are now included in all editions of Qaro’s Code.
ISSOIRE, a town of central France, capital of an arrondissement in the department of Puy-de-Dôme, on the Couze, near its junction with the Allier, 22 m. S.S.E. of Clermont-Ferrand on the Paris-Lyon-Méditerranée railway to Nîmes. Pop. (1906) 5274. Issoire is situated in the fertile plain of Limagne. The streets in the older part of the town are narrow and crooked, but in the newer part there are several fine tree-shaded promenades, while a handsome boulevard encircles the town. The church of St Paul or St Austremoine built on the site of an older chapel raised over the tomb of St Austremoine (Stremonius) affords an excellent specimen of the Romanesque architecture of Auvergne. Issoire is the seat of a sub-prefect; its public institutions include tribunals of first instance and commerce and a communal college. Brewing, wool-carding and the manufacture of passementerie, candles, straw hats and woollen goods are carried on. There is trade in lentils and other agricultural products, in fruit and in wine.
Issoire (Iciodurum) is said to have been founded by the Arverni, and in Roman times rose to some reputation for its schools. In the 5th century the Christian community established there by Stremonius in the 3rd century was overthrown by the fury of the Vandals. During the religious wars of the Reformation, Issoire suffered very severely. Merle, the leader of the Protestants, captured the town in 1574, and treated the inhabitants with great cruelty. The Roman Catholics retook it in 1577, and the ferocity of their retaliation may be inferred from the inscription “Ici fut Issoire” carved on a pillar which was raised on the site of the town. In the contest between the Leaguers and Henry IV., Issoire sustained further sieges, and never wholly regained its early prosperity.
ISSOUDUN, a town of central France, capital of an arrondissement in the department of Indre, on the right bank of the Théols, 17 m. N.E. of Châteauroux by rail. Pop. (1906) 10,566. Among the interesting buildings are the church of St Cyr, combining various architectural styles, with a fine porch and window, and the chapel of the Hôtel Dieu of the early 16th century. Of the fortifications with which the town was formerly surrounded, a town-gate of the 16th century and the White Tower, a lofty cylindrical building of the reign of Philip Augustus, survive. Issoudun is the seat of a sub-prefecture, and has tribunals of first instance and of commerce, a chamber of arts and manufactures and a communal college. The industries, of which the most important is leather-dressing, also include malting and brewing and the manufacture of bristles for brushes and parchment. Trade is in grain, live-stock, leather and wine.
Issoudun, in Latin Exoldunum or Uxellodunum, existed in and before Roman times. In 1195 it was stoutly and successfully defended by the partizans of Richard Cœur-de-Lion against Philip Augustus, king of France. It has suffered severely from fires. A very destructive one in 1651 was the result of an attack on the town in the war of Fronde; Louis XIV. rewarded its fidelity to him during that struggle by the grant of several privileges.
