I believe the title is a quote from Chaucer's translation of Boethius:
þat is to seyn by þe vigour of hys insyȝt while þe soule is in þe body knowen þe þinne subtil knyttynges of þinges.
The Anglo-Saxon letter thorn, þ, is pronounced as the "th" in thorn.
while the letter yogh, ȝ, is a variant of the latin "g" pronounced as the "s" in measure.
The animation plays at 120 counts per minute normally, but the first time through the set the dance will often be slowed down so people can learn the moves more readily. Men are drawn as rectangles, women as ellipses. Each couple is drawn in its own color, however the border of each dancer indicates what role they currently play so the border color may change each time through the minor set.
The dance contains the following figures: turn single, gypsy, cast, lead, hands across, back to back (and probably others).
If you find what you believe to be a mistake in this animation, please leave a comment on youtube explaining what you believe to be wrong. If I agree with you I shall do my best to fix it.
