The Challenge Of Ptolemy

A quick reminder that today at 2pm EST is my first live shiur via Torah In Motion. The topic tonight is (probably) The Challenge Of Ptolemy. Did the Sages of the Talmud believe the world to be flat? In the Talmudic era, the rabbis faced a challenge from Ptolemy in astronomy. The way that they coped with it is remarkably different from how it is commonly portrayed. To watch/listen to the shiur, you have to register with Torah In Motion. For a list of all my classes, many of which will appear as part of this series, click here.
