Lithuanian Talmudist of the seventeenth and eighteenth centuries. He was one of the Ḥasidic party which in 1700 made a pilgrimage to Palestine under the leadership of Judah Ḥasid. In his work "Sha'alu Shelom Yerushalayim" (Berlin, 1716) Semiatitsch gives a full description of this pilgrimage, including the adventures of the party and the death of Judah Ḥasid. He adds an account of the history and a description of the ruins of Jerusalem as well as a list of the sepulchers of the Holy Land, the narrative being followed by some dirges.
