||Kabbalistic discourses on the precepts of on the mezuzah and zizit by R. Nathan Nata ben Reuben David Spira (d. 1666). He was born in Cracow, where his father was a dayyan. His grandfather, after whom he is named, was the Megalleh Amukkot. R. Spira served as rabbi in several locations in Poland prior to settling in Erez Israel, where he became rabbi of the Ashkenaz community. After tach ve-tat (the Chmielnicki massacres of 1648-49) he went to Europe to raise funds for the Jewish communities in Erez Israel, which suffered due to a decline in support because of the devastation in Europe. Among the communities he visited was Amsterdam, where his influence caused Manasseh Ben Israel to bring the plight of Polish Jewry to Oliver Cromwell’s attention. Although he returned to Jerusalem R. Spira again traveled to Europe, where he died in Reggio, Italy.
R. Shapiro's work are mainly on kabbalah: Yayin ha-Meshummar (Venice 1660),on the prohibition against drinking gentile wine (stam yayin) and shaving one’s beard. Italian Jewry was considered lax in their observance of these mitzvot, necessitating this work. These two proscriptions, the former a rabbinic decree based on the Talmud, the other biblical, are codified in the Shulhan Arukh. R. Spira’s approach is kabbalistic, as is that of many of the other contributors to Yayin ha-Meshummar. "Tuv ha-Erez" (Venice, 1655; Zolkiev, 1781), on the excellencies of the Holy Land, on the holy vessels, etc. R. Azulai saw the manuscripts of his religious discourses and of several of his kabalistic works - some were printed at the end of the 19th century.
