Description

Twin revolutions: The 10th century shift to writing running commentaries to gemara, and the 11th/12th century shift to writing dialectic Tosafot. Why did Rabbeinu Gershom and Rabbeinu Chananel start write running commentaries? And why did the generations after Rashi shift to the dialectical style of Tosafot? Note: The history is more overview than granular, and certainly not academic.
