Book excerpt: A collection centered in myth, A Mask for Janus is the 49th volume of the Yale Series of Younger Poets While Merwin's poetry as a whole is grounded in the poetic forms of many eras and societies, this first collection is inspired by classical models. Writing in American Poetry Review, Vernon Young traces the poems to "Biblical tales, Classical myth, love songs from the Age of Chivalry, Renaissance retellings; they comprise carols, roundels, odes, ballads, sestinas, and they contrive golden equivalents of emblematic models: the masque, the Zodiac, the Dance of Death."
