Another small treatise, composed by the same author when he was eighteen years old, is one that bears the title ‪צלצול כנפים‬, and has for its subject “The Defence of Women.” Till about fifteen years ago there was one MS. in existence—that in the Bodleian Library; but Dr. Neubauer published it for the first time in the _Jubelschrift_ (Berlin, 1888), issued by some friends of Zunz on the occasion of his celebrating his ninetieth birthday, under the title of ‪אוהב נשים‬, “The Women's Friend” This title is more appropriate than the one it originally bore, for the simple reason that the treatise in question was evidently written by Yedaya in opposition to another, composed in 1208, by the physician Judah ben Sabbatai, under the title of ‪שונא נשים‬, “The Woman-hater.” This treatise, which Yedaya dedicated to two of his friends, viz. to Meïr and Judah, the sons of Don Solomon Del Infanz, is written in rhymed prose, intermixed with a few short verses. Its style is rather heavy, and all that can be gathered from its subject-matter is this, that a certain king, called Cushan Rishataïm, a great woman-hater, once waged war against an army composed of the friends of womankind, and led by a general named Seria. The latter ultimately defeated the king and his hostile troops, and, out of gratitude for his great victory, he was himself proclaimed king by his own followers. Under his reign a new and happy era opened for the women, who are then wooed and married, and loved more dearly than before; and wedded life is everywhere declared to be the most desirable state of existence. The ‪אוהב נשים‬ closes with the description of the appearance of Judah ben Sabbatai's ghost on earth, and of how it agrees with all Yedaya's statements made there, with the exception of one. Every man, the ghost declares, ought certainly to marry once; but it would be the height of folly on his part if he were to enter again upon the matrimonial state, after his first marriage had turned out a failure.
