Late-antique Israel enjoyed astonishing literary creativity and output in the form of the piyyut, which offered a poetic alternative to the standard liturgical language. The treasures from the Genizah have enriched our knowledge of the paytanim of this period, and important collections of the works of Yosi ben Yosi, Yannai, Shimon bar Megas, and Kallir have been compiled in recent years. But alongside these well-known paytanim were others, often anonymous but sometimes not, thanks to the use of name acrostics, a characteristic style of the piyyut. Numerous compositions identify a paytan whose name was Yehudah, and now his oeuvre has been ably compiled by van Bekkum.
