Fourth Generation of Amoraim

Abaye was head of the academy [in Pumbedita (and in Shir HaShirim, chapter 8, section 2 it says in Nehardea)] in the year 4099, and some say 4096, which is the year 649 according to the Seleucid era [(Tzemach David). This is a scribal error and it should be: Abaye was head of the academy in the year 4085 (when Rav Yosef died) and died in the year 4099 (according to Yuchsin in the order of Amoraim, generation 5, and Shir HaShirim page 35 section 2, he reigned for 14 years), and some say 4096, meaning he died in the year 4096 (according to Rashbag, Rav Yosef died in 634, which is the year 4082, and Abaye reigned after him for 12 years, which is close to 4096, and what Rashbag wrote that Abaye died in 649 is a scribal error, for when you add 12 to 634 it equals 647).

And in Sefer HaKeritot, Abaye died in 660 (i.e., according to the Seleucid era, which is the year 4128, which requires examination). And in Yuchsin in the order of Kabbalah that the Rama copied, it writes "Abaye died, etc." and it is omitted by a scribal error, and it should say Abaye died in the year 4099 and Rava died in the year 4112, for as it is written there, it is certainly an error, and so it is easy to understand (and I found in Responsa 1288 of the Ritzva that Abaye died in the year 4099, and so it says in Yuchsin in the order of Amoraim according to their times, and Abaye lived 60 years (Rosh Hashanah 18b), thus he was born close to the year 4039)].

The Shir HaShirim writes: In the days of Abaye, which was around the year 4085, that is 257 years after the destruction, there was Shavor Malka the Persian, the end of Bava Metzia, who was king of Persia and expert in the laws of Israel. In his days, a philosopher arose in the kingdom of Persia who said there are two gods, one in charge of good and one in charge of evil, and his name was Mani, and he misled many who followed him.

And Shavor Malka sent to entreat him to go with his people to help him, and he went with 400 of his students and hanged them all. And see Akeda, Parashat Vaetchanan, which elaborates on this story [(and the Tashbetz wrote that his name was called Minia)]. In this generation, there was Paulini of the city of Gamon who was born in the kingdom of Naples, and he was the first to ring bells to call people to go pray.

Rava bar Rav Yosef was head in Mechoza after the death of his colleague Abaye in the year 4099, and he reigned for 14 years and died in 4112 according to the Raavad [(Tzemach David, and so it says in Yuchsin in the order of Amoraim according to their times)].
