Two unpublished works of Hebrew grammar by Karaite authors: TROKI, SOLOMON BEN AARON. Rach VeTov. Colophon reads: "Ani Kathavti Shelomo ben Yitzchak Yepheth", pp. (17). * KUKIZOW, MORDECHAI BEN NISAN. Sepher Kelalim. pp. (25)

The cities of Troki (Lith. Trakai) in Lithuania near Vilna, and Kukizow (Krasny Ostrov) near Lvov, were bastions of Karaism in Eastern Europe. Mordechai ben Nisan (17th-century) was Haham of the Karaites at Kukizow. His most famous work, Dod Mordechai (Hamburg, 1714, with Latin translation by J.L. Wolf), a history of Karaism and its doctrine, was written in response to Jacob Trigland of Leiden. His grammatical work, Kelalim is yet unpublished. Solomon ben Aaron lived at Troki in the seventeenth and eighteenth centuries. A relation of Mordecai ben Nisan, Solomon made liberal use of his works. Solomon's most famous work is Apiryon, which provides concise answers to the questions of the Swedish Minister as to the origins of Karaism and its doctrinal differences with Rabbinism. Apiryon was published by Neubauer in Aus der Peterburger Bibliothek (Leipzig, 1866). Another work Rach VeTov, a controversy between the Karaites and Rabbinites in the form of questions and answers, remains unpublished. Our manuscript by that name also takes the form of questions and answers, albeit in regard to Hebrew grammar. See JE, Vol. XII, p. 266; EJ, Vol. X, col. 1288; Vol. XV, cols. 1401-1403.
