Responsa Divrei Yosef, by kabbalist R. Yosef Ergas, author of Shomer Emunim. Livorno: Avraham Meldola, [1742].
R. Yosef Ergas (1685-1730) was a notable Italian kabbalist, author of Shomer Emunim, disciple of kabbalist R. Binyamin HaKohen, the Rabach. He was a rabbi in Pisa, where he established the Neveh Shalom yeshiva before he was appointed rabbi in Livorno (his hometown). R. Malachi HaKohen, author of Yad Malachi was among his leading disciples.
His renowned Shomer Emunim (first printed in Amsterdam 1736) became a basic text of kabbalah. He also authored other works. In his struggle against the Sabbatean Nechemiah Hayyun, he wrote the polemic composition Tochachat Megulah VehaTzad Nachash. R. Ergas' work is conventionally known as Shomer Emunim HaKadmon to differentiate it from a later work by Rebbe Aharon Roth.
