is the art of Hebrew or Aramaic poetry composed either in place of or as adornments to Jewish statutory prayers. Laura S. Lieber uses the of a single poet, Yannai (ca. sixth century C.E.), to introduce readers to this important but largely unfamiliar body of writings. Yannai, the first Hebrew poet to sign his name to his works (by means of an acrostic), influenced Hebrew sacred poetry for centuries beyond his lifespan. He was the first to consistently use true end rhyme, and he was among the first to have written for the weekly service and festivals rather than just particular holidays. As literary works, his poems are as dazzling as they are complex, rich with sound and play, allusion and linguistic beauty. Lieber presents the Hebrew texts of Yannai's 31 extant which embellish the Book of Genesis. She translates, annotates, and analyzes these complex poems, which display the poet's transformative treatments of some of the most familiar biblical narratives. She contextualizes these poems and teaches readers how to read and appreciate by studying Yannai's poetic language and the formal structures of the poems; his exegetical, cultural, and societal importance; and intriguing motifs in Yannai's worldview such as mysticism, holiness, Jewish-Christian relations, and the role of women. Lieber's groundbreaking study is an invitation to those with interests in areas such as liturgical studies, rabbinic literature and targum studies, the early synagogue and its art, Byzantine Christian culture and society, and the history of biblical interpretation to engage with these beautiful and neglected texts and include them in larger intellectual conversations.
