A volume presents previously unpublished poetic fragments attributed to a major Renaissance epic poet, consisting of incomplete cantos that recount the adventures and affections of a chivalric hero. An extended prefatory essay traces the manuscript's discovery, uncertain transmission, provenance in private collections, paleographic challenges, and scholarly debate about authenticity and its relation to the poet's larger epic; the surviving passages show stylistic affinities with the mature work and occasional allusions to contemporary events, but remain fragmentary, corrupted in places, and open to editorial reconstruction.
