Gedulath Mordechai [novellae on the Mordechai’s halachic output]. Appended: Agudath Ezov.

<<Rare.>> The contemporary author, a native of Gnessen (Gniezno, vicinity of Posen) records in the present introduction that he wrote this text after arriving in Prague and encountering there three manuscripts on the Mordechai written by three leading rabbinic scholars: The Mahara’l, R. Yitzchak Chajes (Pachad Yitzchak) and R. Eliezer Aschkenazi (Ma’aseh Hashem). He utilized all these works, to make one new composition “lacking nothing - for a three-fold cord is not quickly broken.” See M. J. Heller, The Seventeenth Century Hebrew Book, Vol. I, pp. 314-5.
