Moses of Kiev

Moses of Kiev was a prominent Jewish Talmudist of the 12th century. His life's work was significantly influenced by the expulsion of Jews from Kiev in 1124, which led him to settle in western Europe. During his time, Moses likely crossed paths with notable scholars, including Jacob b. Meïr Tam, with whom he may have studied. This potential connection highlights Moses' integration into the broader Jewish scholarly community of his era.

Moses of Kiev played a crucial role in facilitating intellectual exchange between Eastern and Western Jewish scholars. He maintained a correspondence with Samuel ben Ali, the head of the Babylonian academy, through which he learned of important legal decisions made by the Geonim. This exchange of knowledge enabled Western scholars to benefit from the insights and rulings of their Eastern counterparts. Moses' interactions with Samuel ben Ali are documented in several notable manuscripts, including Yiḥuse Tanna'im wa-Amora'im, which contains a responsum from Samuel to Moses. Despite his significant contributions, some aspects of Moses' identity remain unclear, including a potential connection to "Rabbi Moses the Russian" mentioned in the Sefer ha-Shoham.
