Compendium of two important Hebrew works on arithmetic, both attributed to a major Jewish scholar of the twelfth century instrumental in bringing Arabic ideas to the West through Spain. The first treatise introduces the decimal system to western Europe. It is extant in 11 manuscripts, last edited in the nineteenth century without its final chapter. The second treatise is entirely unpublished and exists only in a single other, incomplete, copy.

Provenance

1. Written in the Byzantine area, the Balkans or Turkey judging from the script and the paper.

2. Samuel David Luzzato (1800-1865), Italy, Trieste and Padua, his owner’s inscription, f. 1r. Luzzato was an Italian philologist, poet, and biblical exegete, who authored a large number of important writings both in Hebrew and in Italian and who also left a voluminous correspondence.

3. Solomon Hayyim Halberstam (1832-1900), his MS 126, stamped on spine and front pastedown, “126” written in blue pencil and brown ink on recto of front flyleaf. Polish scholar and bibliophile, Solomon Halberstam was a wealthy and avid collector and scholar of Hebrew manuscripts, including codices from Luzzato’s estate and Zunz’s private library.

4. Sir Moses Montefiore (1784-1885), his MS 419, stamped on spine, and front pastedown. Most famous English Jew of his time, Montefiore became a legend in his lifetime, fighting worldwide for the lives and rights of Jews. He founded after the death of his wife Judith Lady Montefiore a college in Ramsgate, which with the appointment of Rabbi Moses Gaster acquired many manuscripts including the Halberstam Collection and the Zunz legacy.

5. London, Jews’ College, on deposit since 1899, as part of the Montefiore Endowment.

Text

ff. 1v-2r, A ledger belonging to a pawnbroker residing in a town in the Byzantine area in the mid-sixteenth century (ff. 2v-6v blank);

ff. 7r-8r, Various extracts including several short polemical dialogues between Jews and Christians, verses and astronomical tables;

ff. 9v-45r, Sefer ha-Mispar, a mathematical work by Abraham ibn Ezra (This manuscript includes an additional chapter, Sha'ar ha-Dagim, not included in that edition [ff. 44v-45r], and some glosses in the margins);

ff. 45v-56v, Hokhmat ha-Mispar, another mathematical work attributed in this manuscript to Abraham ibn Ezra. f. 56, ending with an inscription indicating that a transcription of al-Farabi's Sefer Hathalot[ha-Nimzaot] would be copied on the following leaves, but it was never completed.

Abraham Ibn Ezra (1089-1164), poet, grammarian, biblical commentator, philospher, astronomer, and physician was born in Toledo, Spain. The events of Ibn Ezra's life may be divided into two distinct periods; during the first period he lived Spain and in the second period, from 1140 until his death, he left Spain and traveled widely throughout Europe, to Italy and France and perhaps also to North Africa and Asia. Wherever he traveled he sought the company of scholars. Ibn Ezra left a large body of writings, including biblical exegesis, grammatical treatises, religious philosophy, and he was the author of a number of important mathematical, astronomical, and astrological works, drawn from Arabic sources, including Sefer ha-Mispar. No works by him in Arabic survive, but he surely knew the language.

In the Sefer ha-Mispar Abraham Ibn Ezra is credited with introducing the Indian-Arabic decimal system of enumeration to Europe. He uses the Hebrew letters Aleph to Tet as the equivalents of the Arabic numerals one to nine and as the components of all larger numbers. He employs the use of a circle for the zero symbol. Later chapters deal with different mathematical operations, such as addition, subtraction, multiplication, division, fractions, proportions, square roots, geometry, etc. (see Levy, p. 43, nos. 50-51).

The provenances and origins of the eleven extant manuscripts of the Sefer ha-Mispar reflect a widespread transmission of the text. They were written in Italy, Ashkenaz (German area), Turkey, and Spain from the fourteenth to the sixteenth centuries, and there is even a copy by a Karaite around 1600 in Turkey. Two of the nine copies were transcribed in early nineteenth-century Italy, and the work was not printed until its edition in the late nineteenth century. The critical edition of Sefer ha-Mispar published in Frankfurt in 1895 with a commentary and a German translation made use of this manuscript for variants, although it did not publish the additional chapter Sha'ar ha-Dagim (ff. 44v-45r). Ibn Ezra’s Hokhmat haMispar remains unstudied, and it has never been published. The only other known copy in Cambridge University Library, Add. 481, ff. 53v-55v is incomplete and is not attributed to ibn Ezra (see Stefan C. Reif, assisted by Shulamit Reif, Hebrew Manucripts at Cambridge University Library: a Description and Introduction, Cambridge, Cambridge University Press, 1997, no. SCR 581).
