Koppelman (1555-1594) was a Talmudic scholar distinguished for his broad erudition and interest in secular sciences. Jacob was born in Freiburg and studied under Mordecai Jaffe. Early in his life he embarked upon mathematical and astronomical studies, in addition to intensive occupation with traditional Jewish learning. In this work he elucidates the laws relating to geography and establishes the various weights and measures in the Talmud. As well he draws the site of the Temple, the candelabrum, the table of showbread, revealing considerable knowledge in all these fields.
