Jew of the Week: Abraham Zacuto

The Rabbi Who Saved Columbus

A page from Zacuto’s astronomical tables

Avraham ben Shmuel Zacut “Zacuto” (1452-1515) was born in Salamanca, in what is today Spain, to a religious Sephardic Jewish family. He studied both Jewish law and astronomy, becoming the rabbi of Salamanca and simultaneously an astronomy teacher. He invented a new type of astrolabe and a novel method for determining latitude at sea, which would become vital to navigators and sailors. In 1478, he published HaChibur haGadol, “The Great Book”, with detailed and easy-to-use astronomical tables. It was translated to Spanish in 1481, and Latin shortly after. This made Rabbi Zacuto world-famous and when the Jews of Spain were banished in 1492, he was immediately hired by King John II of Portugal to serve as his royal astronomer. Zacuto argued that a sea route to India was possible, and this convinced John II to finance Vasco da Gama’s famous voyage to discover the route to India, opening European sea trade with the Far East. Da Gama used Zacuto’s astrolabe and tables, and Zacuto personally trained and taught the sailors. Zacuto had also argued, based on the Zohar—the “textbook” of Jewish mysticism, dating back to Rabbi Shimon bar Yochai in the 2nd century CE—that the Earth must be spherical, and it would be possible to journey west, not east. This information was instrumental in convincing Christopher Columbus to launch his own voyage. In fact, Columbus relied heavily on Zacuto’s astrolabe and astronomical charts. In a well-known story from his third voyage, Columbus was marooned on a Caribbean island and facing both hostile natives and his own rebellious sailors. The natives refused to provide food and resources to Columbus, so he came up with a ruse. Consulting Zacuto’s tables, Columbus saw that a lunar eclipse was imminent. He told the native chief that if he will not provide resources to the sailors, the moon would go dark and God would punish them! The eclipse came and the natives panicked, giving Columbus’ men all that they needed to survive. Back in Europe, the next king of Portugal, Manuel I, followed the Spanish in expelling his Jewish subjects. Zacuto was offered to stay in Portugal if only he converted to Christianity, even just nominally. Of course, he refused, and left with his people. He first settled in Tunis, where he wrote his monumental Sefer Yuhasin, a highly-acclaimed work describing the entire history of the Jewish people. He later fulfilled his dream of making it to the Holy Land and lived his last years in Jerusalem. Rabbi Zacuto is considered one of history’s greatest and most consequential astronomers. The Zagut Crater on the moon is named after him.

The blessing in life is when you find the torture you are comfortable with. That’s marriage, it’s kids, it’s work, it’s exercise. Find the torture you’re comfortable with and you’ll do well. You’ve mastered that, you’ve mastered life.

Jew of the Week: Moses Mendelssohn

Father of Jewish Enlightenment 

Moshe ben Mendel (1729-1786) was born in the Germanic municipality of Dessau to an impoverished, religious Jewish family. His father was a sofer (a Torah scribe), and trained young Moshe in the scribal arts, as well. Moshe also learned Torah and Talmud with Rabbi David Frankel. When Frankel took up a rabbinic post in Berlin, Moshe moved with him to the capital. To keep him safer and open more opportunities, his father had asked him to make his name more German-sounding, resulting in the name Moses Mendelssohn (“son of Mendel”). Mendelssohn continued in his rabbinic studies with the intention of becoming a rabbi, but also took up the study of mathematics, Latin, and philosophy. He soon began learning French and English as well, with an influential Jewish physician and tutor. That tutor introduced Mendelssohn to renowned German philosopher and writer Gotthold Ephraim Lessing. The two became good friends, and Mendelssohn inspired Lessing’s popular play Nathan the Wise. Mendelssohn’s genius soon spread throughout the secular world, and he even won the top Berlin Academy prize for mathematical proofs of metaphysics (second place went to Immanuel Kant!) In 1763, the King of Prussia granted Mendelssohn the special status of schutzjude, “Protected Jew”. At a time when secularism and atheism were sweeping Europe, Mendelssohn remained a believer and resolved to convince the masses On the Immortality of Souls, published in 1767. The treatise became so popular that people began calling him the “German Plato” and the “German Socrates”. In 1775, an order of expulsion was being drawn up against Swiss and German Jews, so Mendelssohn intervened to get the expulsion rescinded. Mendelssohn was constantly mired in theological debates with his German acquaintances, and often pressured to convert to Christianity. He resisted and defended his faith. Nonetheless, the stress was so great on him that he eventually fell deeply ill and was bedridden. At this point he resolved “to dedicate the remains of my strength for the benefit of my children or a goodly portion of my nation”. To make it more accessible to a wider audience, he started a new German translation and commentary of the Torah. The resulting Biur was hugely popular, and received approbations from many rabbis. Meanwhile, he worked to get various restrictions on Jews repealed, and played an instrumental role in getting Jews in Europe basic human and civil rights. In his Jerusalem, he argued passionately for freedom of religion, and for the Christian authorities to leave the Jews alone. Mendelssohn corresponded with one of the leading sages of the day, Rabbi Yakov Emden, and wrote how he “thirsted” for the rabbi’s teachings. Intriguingly, while Rabbi Emden had criticized the Zohar (the famous “textbook” of Jewish mysticism), Mendelssohn actually defended its authenticity. He also defended the authenticity of nikkud, the traditional Hebrew vowel system. Although he was widely admired and respected in his own day, Mendelssohn’s work opened up the door to more Jews learning secular subjects and entering mainstream society, which led to wider assimilation. Four of his own six children ended up converting to Christianity, and just one grandson remained Jewish. (Another grandson was renowned composer Felix Mendelssohn.) Mendelssohn was later credited with being the “father of Haskalah”, the so-called “Jewish Enlightenment”. Because of this, in the decades after his death he became something of a villain in the Orthodox world, and any positive mention of his name was expunged. Today, he is still viewed negatively in religious Jewish circles, although he had truly done a great deal on behalf of the Jewish people.

Jew of the Week: Shimon Lavi

Father of Libyan Jewry

Shimon ibn Lavi (1486-1585) was born in Spain and exiled with his family during the Spanish Expulsion of 1492. The family settled in Fez, Morocco, where Lavi studied to become a rabbi. He then sought to make aliyah to the Holy Land, but was kidnapped along the way near Tripoli by Arab brigands. After being ransomed, he found the Tripoli Jewish community in need of a rabbi so he stayed there. It was Lavi who opened the city’s first yeshivas, established a beit din, and went on to make the city one of the largest Jewish communities in North Africa. He is often credited with being the “father of Tripoli Jews”. Rabbi Lavi was the community’s official representative to the government, and served as the Ottoman governor’s personal physician. He was also a major Kabbalist, alchemist, and mystic. In fact, he wrote the popular song “Bar Yochai”, in honour of Rabbi Shimon bar Yochai whose teachings would become the Zohar (the primary “textbook” of Kabbalah) and who is celebrated on Lag b’Omer. Lavi wrote a commentary on the Zohar called Ketem Paz, as well as a dictionary translating some of the Zohar’s most cryptic words. He was widely known as a miracle worker, and was revered by Jews and Muslims alike (the latter refer to him as “Ibn Limam”), with his tomb serving as a major pilgrimage site in Libya.

One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth. The bamboozle has captured us. It’s simply too painful to acknowledge, even to ourselves, that we’ve been taken. Once you give a charlatan power over you, you almost never get it back.
