Rabbi El’azar Berabbi Qillir (commonly known as “HaQallir”) was the most famous and productive of the Hebrew poets during the peak era of early Hebrew piyyut (liturgical poetry) between the sixth and eighth centuries AD. Of the thousands of poems he penned, some were preserved in the Asheknazi, French and Italian mahzorim (prayer books) for the High Holy Days, and a few of them are recited in synagogues to this day.
