For forty years, American priest and friar Reginald Foster, O.C.C., worked in the Latin Letters office of the Roman Curia's Secretary of State in Vatican City. As Latinist of four popes, he soon emerged as an internationally recognised authority on the Latin language - some have said, the internationally recognised authority, consulted by scholars, priests, and laymen worldwide. In 1986, he began teaching an annual summer Latin course that attracted advanced students and professors from around the globe. This volume gathers contributions from some of his many students in honor of his enduring influence and achievements. Its chapters explore a wide range of linguistic and literary evidence from antiquity to the present day in a variety of theoretical perspectives. If the motivation for putting together this collection has been to reflect (and reflect upon) Foster's influences on Latin scholarship and pedagogy, its title alludes - via the medieval folk etymology of the word "labyrinthus" ("quasi labor intus") - to its theme: ambiguity in Latin literature.
