Yehudah ben Hillel haLevi

Yehudah ben Hillel haLevi (also Yehudah haLevi ben Rabbi Hillel, fl. 11th c.), a medieval paytan of the Kalir school, some of whose work was discovered in the Cairo Genizah. His piyyutim are based on customs prevailing in Erets Yisrael, indicating that he lived there or in Egypt. He is the only paytan known to have composed piyyutim for Tu biShvat. Two of his ḳerovot for the Shemoneh Esreh are preserved; one, published by Menachem Zulay (Leket Shirim u-Fiyyutim (1936)) contains names of trees growing in the Land of Israel.
