Astronomical Lore in Chaucer

In medieval England, the stars were not distant abstractions but active participants in human affairs. Physicians read the heavens before drawing blood; farmers planted by planetary position; kings waged war under auspicious constellations. Geoffrey Chaucer wrote from within this cosmic framework, and to read him without understanding the celestial logic that shaped his sentences is to miss the machinery of his meaning. Florence M. Grimm's 1922 study reconstructs that lost intellectual world, tracing the astronomical and astrological references woven through the Canterbury Tales, Troilus and Criseyde, and Chaucer's scientific treatises. She shows how the geocentric universe, a cosmos with Earth at its center and the planets wheeling above in moral significance, was not mere backdrop but the very grammar through which Chaucer's audience understood fate, character, and consequence. This remains essential reading for anyone who takes Chaucer seriously: a guide to the celestial code that made his jokes land, his tragedies resonate, and his pilgrims see the world as they did.
