Allemande

[…] sweet to us it is to behold delightful dancing, be it the stately splendour of the Pavane which progresseth as large clouds at sun-down that pass by in splendour; or the graceful Allemande; or the Fandango, which goeth by degrees from languorous beauty to the swiftness and passion of Bacchanals dancing on the high lawns under a summer moon that hangeth in the pine trees; or the joyous maze of the Galliard; or the Gigue, dear to the Foliots.

The gaudy splashes of lightning made it seem that some weird dance was going on, one where you threw your partner into the nearest tree instead of allemanding her, or dug your knee into his crotch instead of doing a do-si-do.
