* About the author: Isaac (Yhsak) de Acosta (?- d. 1728), was a French Sephardi rabbi. Probably a native of Amsterdam, Acosta became hazzan of the Jewish community of Peyrehorade, near Bayonne, formed by Marrano fugitives from the Iberian Peninsula. His "Historia Sacra Real" (1691), dedicated to the wardens of the community, is one of the earliest manifestations of Judaism in this place. Later (apparently after an interlude in Biarritz) he succeeded R. Hayyim de Mercado as hakham at Bayonne, where he composed his handbook for the administration of the last rites to the dying, "Via de Salvacion" (1709; reprinted by M. Kaplan, Bayonne, 1874), and his major work, "Conjeturas Sagradas" (Leyden, 1722), a commentary in Spanish on the Early Prophets, based on the classical Hebrew commentators and the Midrash.
