The Rashbash on Rosh Hashanah

Oxford University Press recently published a book with Jewish stories and folktales titled Leaves from the Garden of Eden. I haven't seen the book but this excerpt contains a Rosh Hashanah story about the Rashbash, his father the Rashbatz, and their legendary miraculous rescue from imprisonment (link).

The Rashbash, by the way, has a fascinating responsum about the theology of Rosh Hashanah (no. 195) -- can someone successfully run away from danger or is his fate pre-determined.
