Last May, Spenserians lost one of the most widely admired teachers and scholars of  his generation.  In his memory, The Spenser Review offers retrospective appreciations of Alpers’s two major works, The Poetry of  The Faerie Queene and What is Pastoral?, by a cohort of scholars from Europe, Asia, and North America:  Sukanta Chaudhuri, Andrew Escobedo, Paul J. Hecht, James Nohrnberg, Syrithe Pugh, and Christopher Warley.
