The Book of Formation

There is a much-studied document in Jewish literature whose origin is unknown. It has been considered the work of a 1st-century Rabbi Akiva, or the first man Adam, or the patriarch Abraham. The Jewish Encyclopedia claims it is more likely a work of the 3rd or 4th century based on its form of Jewish gnosis. It is the Sefer Yetzirah, sometimes called the "Book of Creation" but more accurately the "Book of Formation."

Not only is its origin a topic for debate, so is its purpose. It has been considered to be a mystical work about the Kabbalah, an explanation of how the universe came to be, and a work about linguistic theory. Each of these theories can be supported by its opening statement:

By thirty-two mysterious paths of wisdom Yah has engraved [all things], [who is] the Lord of hosts, the God of Israel, the living God, the Almighty God, He that is uplifted and exalted, He that Dwells forever, and whose Name is holy; having created His world by three [derivatives] of [the Hebrew root-word] sefar : namely, sefer (a book), sefor (a count) and sippur (a story), along with ten calibrations of empty space and twenty-two letters [of the Hebrew alphabet], [of which] three are principal [letters] (i.e. א מ ש‎), seven are double-sounding [consonants] (i.e. בג"ד כפר"ת‎) and twelve are ordinary [letters] (i.e. ה ו ז ח ט י ל נ ס ע צ ק‎).

(This idea, that the Hebrew alphabet is the guide to God and the universe, found new life in the Modern Era in something called the Bible Code.)

There are different versions of it extant that have been annotated by different scholars. One shorter version annotated by Dunash ibn Tamim, a pupil of Isaac Judaeus, argues that Hebrew was the original universal language and Arabic is derived from it. He states:

If God assists me and prolongs my life, I shall complete the work in which I have stated that Hebrew is the original tongue of mankind and older than the Arabic; furthermore, the book will show the relationship of the two languages, and that every pure word in the Arabic can be found in the Hebrew; that the Hebrew is a purified Arabic; and that the names of certain things are identical in both languages.

A bold claim. The Sefer Yetzirah is the subject of almost as much speculation and annotation as the Bible. We'll continue our exploration of it tomorrow.

Isaac Judaeus

An Andalusian Arab named Ibn Juljul wrote Ṭabaqāt al-aṭibbā’ w’al-hukamā’ ("Generations of Physicians and Wise Men") in the late 900s. It is one of the only sources for biographies of several early scholars, philosophers, and doctors. In it we learn details about the life and career of Isaac Israeli ben Solomon, who is sometimes called simply Isaac Judaeus.

He was born in Cairo and became known as an oculist (we've talked about medieval eye treatment before).  About 904 he became the court physician to Prince Abu Mudhar Ziyadat Allah III in Kairouan, capital of Tunisia. He studied general medicine while there.

After the death of Ziyadat in 909, Isaac became doctor to Caliph 'Ubaid Allah al-Mahdi, the founder of the Fatimid dynasty. The caliph enjoyed the witty repartee of his Jewish physician. Isaac began lecturing on medicine, and many people came to hear him speak as his fame spread. He continued to learn, studying astronomy, mathematics, medicine, and natural history.

He wrote medical manuals in Arabic which, in the Arabic-speaking world, were considered gems, but were unknown in Western Europe. The 12th century saw translators in Toledo striving to make many works available to a wider audience. Gerard of Cremona translated Isaac's Liber de Definitionibus (Book of Definitions) and Liber Elementorum (Book on the Elements) into Latin. Christian scholars started noticing his work, such as Albertus Magnus, Aquinas, Roger Bacon, Nicholas of Cusa, and Vincent de Beauvais.

One of his works dealt with the urinary tract, which I covered a few years ago.

The years of his life are given as different dates according to the source. Encyclopedia Britannica says born 832/855, Egypt—died 932/955) and that he lived more than 100 years. His death has been declared as 932, 940, 942, 950, and 955.

One of his pupils, Dunash ibn Tamim, wrote a commentary on a work of Jewish mysticism that quotes Isaac so extensively that later scholars thought it was written by Isaac himself. Dunash and this work, the Sefer Yetzirah, will be our next line of topics.
