An alternative methodology for the classification and study of 12th- to 15th-century manuscripts is set forth in these articles by a global team of philologists. Concentrating primarily on investigations of medical and literary manuscripts written in medieval English, these works address the primary structure motivating the syntactic behavior of verbs in Old English speech; morality and female sexuality in late medieval English scientific treatises; patterns of orality; and the complicity of the audience in Chaucer's Troilus and Criseyde. Swaying from traditional approaches, these essays consider the subjects from an interdisciplinary perspective, not only in terms of the relationship of philology to other subjects but also within philology in its analysis of speech, syntax, morphology, and semantics. Subjects previously thought unsolvable are given a fresh look in this multifaceted approach.
