Halachoth Ketanoth [responsa, including shemoth gittin (a list of proper names as required in a Bill of Divorce]

Known for its succinct style and clarity, this work of responsa “yields the most insight into the life of Jacob Hagiz...from its pages one can catch glimpses into his personality, his relationships with his disciples, and the scope of the activities of his yeshiva.” See E. Carlebach, The Pursuit of Heresy: Rabbi Moses Hagiz and the Sabbatian Controversies (1990) pp. 26-29. Halachoth Ketanoth was issued by the Author’s son, R. Moses Hagiz - famous for his dogged pursuit of crypto-Sabbatians. Ironically Jacob Hagiz directed the yeshivah in Jerusalem where Nathan of Gaza, prophet of Shabbetai Zevi, studied as a young man. Later, Jacob Hagiz vehemently repudiated his former student. See A. Yaari, Sheluchei Eretz Yisrael (1977), pp. 290-29; Gershom Scholem, Sabbatai Sevi (1973), pp. 201-02, 246-48
