Thanks for the advice. I'll see if I can find a copy of that book. I suspect one of my Roman dance reenactor friends may already have it, as we approach this highly speculative idea from lots of different directions. What I'm particularly hoping to come up with are folk dances that people did together, as women and men. Most of the efforts at Roman dance thus far have been dances done by women only. Part of this is because the surviving literature tells us that upper class Roman men Just Did Not Dance, as it was considered beneath their Dignitas. But we know that some, such as Lucius Cornelius Sulla, did dance quite frequently. So I'm working from the idea that the rule was kept as much in the breach as in the keeping. But it's devilish impossible to find anything that they actually danced.
