Aquillia

The first Couple lead up, the second Couple lead down, turn about and lead; the first Couple cast off into the second Couples place, do this to the last. The first Couple take Hands and change places, the first Man and second Woman take Hands, and the first Woman and second Man take Hands and change places, then take Hands with your own and change places, do this to the last. The first Man cast off, his Woman following him into second place, so going the Figure of Eight, the Woman cast off, and does as much, do this to the last.

I had thought multi part dances had died out by the time John Young took over the Dancing Master, but here is a three part dance, each part ending with the phrase do this to the last meaning that each part should run until everyone returns to their starting positions.

The music is a single 8 bar strain.

The first part: The first Couple lead up, the second Couple lead down, turn about and lead; the first Couple cast off into the second Couples place, probably takes 2 bars to lead away, 2 to lead back and then four bars to cast down/lead up

The second part: The first Couple take Hands and change places, the first Man and second Woman take Hands, and the first Woman and second Man take Hands and change places, then take Hands with your own and change places can also fit in 8 bars. First the 1s do a two hand turn half to cross the set. Then a two hand turn half on the woman's line (M1+W2). Another on the men's (W1+M2). And finally the 1s again turn half to become proper.

The third part: The first Man cast off, his Woman following him into second place, so going the Figure of Eight, the Woman cast off, and does as much seems to need two strains and would be a double progression dance. That's unlikely. Better to think of it as alternating who leads the figure, then each piece fits into a single strain (as all the other parts did).
