The New Astronomy: Brahe & Kepler in Prague
Chaucer’s Use of Astronomy in the Canterbury Tales
This video is an adaptation of one of my more recent SCA classes. It was prepared for a Canterbury Tales themed event last September, but I’d held off on converting it into a video, because I thought it would be appropriate to release the video on April 18th: The date of the pilgrimage Chaucer gives.

But how did I do with astronomy? Continue reading “2025 in Review”
