OK, so to sum up: We have a large number of people, men and women, dancing, but not in couples. They’re not dancing to entertain an audience, and indeed, no audience need even be present. The dance involves music and a specific instrument, which is a stringed instrument, possibly played by multiple people. They’re not dancing for religious purposes, nor is the dance related to any astronomical cycle. The dance was certainly performed in the 1400s, and possibly for a few centuries after that. The dance is associated with a specific location, but apparently incorrectly.
