The Rosh was probably born in
Cologne,
Holy Roman Empire, and died in
Toledo. His family was prominent for learning and piety, his father Yechiel was a Talmudist, and one of his ancestors was Rabbi
Eliezer ben Nathan (the
RaABaN). Asher had eight sons, the most prominent of whom were
Jacob (author of the ''
Arba'ah Turim'') and
Judah. In 1286, King
Rudolf I had instituted a new persecution of the Jews, and the great teacher of the Rosh, Rabbi
Meir of Rothenburg, left Germany but was captured and imprisoned. The Rosh raised a ransom for his release, but Rabbi Meir refused it, for fear of encouraging the imprisonment of other rabbis. Thereafter the Rosh assumed Rabbi Meir's position in Worms. He was, however, forced to emigrate (in all likelihood, a victim of blackmail by the government, aimed at acquiring his fortune). After leaving Germany, he first settled in southern
France, and then in
Toledo,
Spain, where he became
rabbi on the recommendation of
Rabbi Solomon ben Abraham Aderet (
RaShBA). Rabbenu Asher's son Judah testified to the fact that he died in poverty. Rabbeinu Asher died in Toledo on 9
Cheshvan 5088 (1327 CE). His known surviving children were said to have been killed in the ensuing persecutions that affected Spain in 1392. Rabbenu Asher possessed "methodical and systematic" Talmudic knowledge, and was distinguished for his ability to analyze and thereby clarify long
Talmudic discussions. The Rosh was known for his independent legal reasoning: "We must not be guided in our decisions by the admiration of great men, and in the event of a
law not being clearly stated in the Talmud, we are not bound to accept it, even if it be based on the works of the
Geonim." (For instance, the Rosh ruled that the
liturgy of the Geonim was not subject to the Talmudic rule against change in the
prayers.) Rabbenu Asher was opposed to the study of secular knowledge, especially
philosophy. He held that philosophy is based on
critical research, whereas religion is based on
tradition and the two are thus "incapable of harmonization". He said that "none that go unto her may return"—in fact, he thanked
God for having saved him from its influence, and boasted of possessing no knowledge outside the
Torah. He attempted to issue a decree against the study of non-Jewish learning. One effect of this attitude was to limit his influence on
secular Spanish Jewry. At the same time, within rabbinic circles, "he transplanted the strict and narrow Talmudic spirit from Germany to
Spain", and this, in some measure, turned Spanish Jews from secular research to the study of the Talmud. ==Works==
