רב (אַבָּא אריכא)

Rav Abba bar Aybo (Aramaic: רַב אַבָּא בַּר אִיבּוֹ; 175–247 CE), commonly known as Abba Arikha (אַבָּא אריכא) or simply as Rav (רַב), was a Jewish amora of the 3rd century. He was born and lived in Kafri, Asoristan, in the Sasanian Empire. In Sura, Arikha established the systematic study of the rabbinic traditions, which, using the Mishnah as a foundational text, led to the compilation of the Talmud. With him began the long period of ascendancy of the prestigious Talmudic academies in Babylonia around the year 220. In the Talmud, he is frequently associated with Samuel of Nehardea, a fellow amora with whom he debated many issues.
