Errant, Gabriel Levin's sixth collection, opens and ends with invocations: of Venus at dawn and Hesperus at dusk. The book's day takes us on a three-part planetary journey. "What Drew Me On" is inspired by a friend's free-floating works on paper and by Plato's image of the music of the spheres. Ghostly presences are evoked in several poetic forms, including terza rima stanzas chronicling how image-making evolved. "First came sooty beings shinnying up walls." There are elegies to the cineastes Abbas Kiarostomi and Chantal Akerman, translations from French and Greek, and (in villanelle form) from the Medieval Hebrew of Avraham Ibn Ezra. There are aubades, lyrics, and a sequence arranged in short-lined triads of psychic retreat in Jerusalem. The wanderer picks up where he left off in earlier books, striking out from home, conjuring Sa'adi's Gulistan or Nasir-i Khursaw in Cairo; pocketing bits of obsidian on the island of Melos, paying homage to Yannis Ritsos in Crete.
