About the Tosafos Yom-Tov, Wikipedia writes:
the Megillah that Heller wrote, called Megilat Eivah (Scroll of Hostility), that tells the story of his imprisonment and release, became a tradition for the descendants of Rabbi Heller. To this day, they celebrate the story of his life in a special Purim celebration.
In 1984 on the 330th anniversary Yahrzeit of Rabbi Heller's death his autobiographical story of his imprisonment Megillat Eivah and a detailed family tree were published in English by Rabbi C.U. Lipschitz and Dr. Neil Rosenstein under the title, The Feast and The Fast by Moznaim Publishing Corporation, New York and Jerusalem.
Is this megilla available online anywhere, in original or English?
