Abba Gorion of Sidon
Abba Gorion of Sidon was a tanna, who lived in the second century. He handed down sayings from both Abba Saul (Mishnah, Ḳid. iv. 14, Yerushalmi version) and Rabban Gamaliel II. The quote from Gamaliel, was used in the introduction to a Midrash on the Book of Esther, for which reason the latter was called Midrash Abba Gorion.
