PORTO, Italian family prominent during the 16th and 17th centuries. Its members were scattered in various Italian towns, notably Mantua, Venice, Verona, and Rome. The family originated in Germany, from the Rafa (Rabe, "raven") family, which settled in the town of Porto in the province of Verona, and from which the noted *Rapoport family was descended. Its members include Abraham Menahem ben Jacob ha-Kohen *Porto, one of the heads of the family. ABRAHAM (d. 1593) was a rabbi of Mantua, and author of Ammudei ha-Golah (in manuscript). His sons were JEHIEL (1532–1577), a pupil of Meir *Katzenellenbogen of Padua, and GERSHON (1538–after 1593), also a scholar of Mantua. Gershon's son, SIMḤAH, was a pupil of Samuel Judah Katzenellenbogen in Venice, where he worked as a proofreader until 1589. In 1602 he left for the Moravian town of Prossnitz (Prostejov), where he published Kol Simḥah (1603), a rhymed work on the Sabbath laws. From there he went on to Vienna.
Other members of the family include MENAHEM ZION (EMANUEL) PORTO (d. c. 1600), rabbi and mathematician.
