Daf 17 of masechta Avodah Zarah tells several important and somewhat well known stories. The first, is the story of when Rabbi Eliezer was arrested by heretics for the capitol offense of studying the holy Torah. Wel also learn of the story of Rabbie Elazar ben Dordaya who repented at the last moment and was admitted to the world to come. The daf ends off with the story of Rabbis Chanina ben Teradyon and Elazar ben Perata, who were arrested by the Romans for studying Torah (among other offenses). Very interesting daf here on Babble on Talmud. Enjoy.
