This book is a supplement to the eighteen-volume edition of the Complete Works of Philip von Zesen (1619-1689). For the first time, it presents the diverse oeuvre of the Baroque "poeta doctus" in monograph form, and explores its historical and literary contexts. The works considered include von Zesen's lyric poetry, poetics, novels, historical works, astronomy, philological research on myths, translations, devotional works, and writings on toleration.
