note that Hadassi included in his "Eshkol" the first grammatical work of Abraham ibn Ezra, without acknowledgment. In attacking the Rabbanites, he followed the example of his predecessors, as Solomon ben Jeroham, Japheth ben Ali, Sahl ben Matzliah, and others. This work was printed at Eupatoria (1836), with an introduction by Caleb Afendopolo entitled Nahal Eshkol. Alphabets 99-100 and part of 98 were excluded from this edition by the censor, but have been published by Bacher in J. Q. R. Hadassi mentions a previously written work of his entitled Sefer Teren bi-Teren, a collection of homonyms which, he says, was an addition to the eighty pairs of Ben Asher (alphabets 163 ב, 168 ס, 173 נ). There exists also a fragment which Abraham Firkovich entitled Sefer ha-Yalqut and attributed to Hadassi, while Pinsker regarded it as an extract from Tobiah's Sefer ha-Mitzvot. P. F. Frankl, however, agreed with Firkovich in regarding it as a part of the "Eshkol ha-Kofer," which Hadassi had previously written in prose. In the Karaite Siddur there are four piyyutim by Hadassi.
