ABRAHAM KOHEN DE HERRERA. Beth Elo-him [detailed kabbalistic discourses]

Descended from a noble Marrano family: "Migolei Yerushalayim Harishon...BeSephard" (From Among the First Exiles of Jerusalem in Spain), the Author studied Kabbalah under the guidance of R. Yisrael Sarug, one of the major disciples of Isaac Luria. De Herrera was the first to undertake a systematic philosophical interpretation of kabbalistic thought presenting a reasoned developement of such doctrines as Tzimtzum and Kelipah. He originally wrote in Spanish and his works were translated into Hebrew by Rabbi Isaac ABOAB dA FONSECA, one of the Netherland’s most esteemed rabbinic leaders. (In 1651, dA FONSECA accepted a call as Haham to Recife, Brazil, thus becoming the first Rabbi to minister on the American Continent) De Herrera was held in high esteem by Menasseh ben Israel, indeed he provided an approbation to Menasseh's Conciliador in 1632
