Sepher HaZichronoth [ethics].

A work of practical halacha (Halakha LeMa’aseh) concerning which questions exist as to the exact authorship of the book. It is attributed alternatively to Samuel ben Abraham Aboab or to Isaac ben Abraham Hayim Jesurun of Hamburg (d. 1655). The final four leaves of the book transcribe a lengthy admonition of Rabbi Judah Löw (MaHaRa”L) of Prague concerning the drinking of stam yeinam (non-Jewish wine). Prof. Haym Soloveitchik has discussed at length that Italian and also Moravian Jewry were lax in this respect, and how halakhists dealt with such a challenge to traditional observance. See H. Soloveitchik, Principles and Pressures: Jewish Trade in Gentile Wine in the Middle Ages (Tel Aviv, 2003) p. 118, n. 76.
