Rabbi Shachna was distinguished above all the men of his generation, and his reputation spread from the rising of the sun to its setting. He was one of the great students of Yaakov Pollak, mentioned above [(see year 5290)], and he was a head of the rabbinic court in the community of Lublin and died in the year 5317 [(and in Sha'arei Kedusha 64, page 71: HaRav Rabbi Shalom bar Yosef known as Rabbi Shachna, a great gaon; Rabbi Shmuel his son; Rabbi Yonah bar Kalman of Brashia was the disputant of Rabbi Shachna)].
