Astronomical Lore in Chaucer

A scholarly survey of astronomical and astrological material in Chaucer’s writings, placed within the intellectual and practical context of the Middle Ages. The study shows Chaucer’s acquaintance with geocentric cosmology, planetary qualities, solar declination, lunar phases, and tables used for timekeeping, and it explains how celestial concepts mark seasons, measure intervals, and inform moral or character description. Separate sections assess the poet’s scientific sources and knowledge, analyze cosmology and explicit astronomical passages, and catalog astrological lore, with supporting textual readings and an appendix of technical material.
