Samuel ibn Naghrela (Hebrew: שמואל הלוי בן יוסף הנגיד‎, Sh'muel HaLevi ben Yosef HaNagid; Arabic: أبو إسحاق إسماعيل بن النغريلة‎ Abu Ishaq Isma'il bin Naghrillah), also known as Samuel HaNagid (Hebrew: שמואל הנגיד‎, Shmuel HaNagid, lit. Samuel the Prince), 993-1056, was a Talmudic scholar, grammarian, philologist, poet, warrior, and statesman, who lived in Spain at the time of the Moorish rule. Born in Mérida, his main poetic works include "Ben Tehillim" (Son of Psalms), "Ben Qoheleth" (Son of Ecclesiastes), and "Ben Mishlei" (Son of Proverbs), each of which imitates the "father work". His choice of poetic themes reflected his myriad occupations and personal world-view, including poems describing the battlefield using the analogy of a game of chess, poems speaking of the great beauty of nature, of which there are numerous, etc. His power in word choice of poetic portrayal of nature rivals that of the other great Jewish poets, namely ibn Saruk. He founded the Yeshiva that produced such brilliant scholars as R' Yitschak ibn Gias and the Rambam (Maimonides)'s father. The "Introduction to the Talmud" is erroneously attribuited to Shmuel.
