This supposed discovery gave a new impulse to Menasseh"s Messianic hopes. Menasseh wrote a book about this narrative, The Hope of Israel. In it Menasseh argued, and tried to give learned support to the theory that the native inhabitants of America at the time of the European discovery were actually descendants of the Ten Tribes of Israel.
The book was originally written in Hebrew (Mikveh Israel) or in Latin (Spes Israelis) around 1648, but its publication in English in 1650 in London caused great controversy and polemics in England.
