Rash MiShantz

Klalim

1. R' Shimon of Shantz, also known as the Rashba or Rash MiShantz, was a Talmid of the Ri Hazaken and brother of the Ritza.
2. When elucidating a Mishnah, R' Shimshon a number of times first presents the explanation that seems correct but then negates it by quoting the Gemara's explanation.
3. There's a debate if the Rash ever saw the Rambam's Perush HaMishnah, because he never quotes it in his own commentary, yet, he apparently discuss it in letters with other Rishonim.
