this seems to lend to the morris dancers (male leaping dancers of the time). these men were part of the entertainment during dinner. the morris dancers would preform between courses at feasts.
morris dancers were popular during this time. this wild and strenuous dance probably came from ancient war and fertility dance. it was a popular form of dance in the 15th and 16th centuries - maybe even before.
the ladies dancing from yesterday were ladies attending the feast, dancing socially. these dancers refer to the hired entertainment.
the 10 lords a-leaping refer to the 10 commandments in the christian interpretation.
