One impression that stands out from this collection is the extent to which improvisation was an important factor in all of the arts. As each of the authors assembles a case by ferreting out bits and pieces of information having to do with a single art, the weight of the assembled material lends additional strength to each case. By considering the overall picture that results, as well as that made by each of the individual studies, the reader is able to see much more clearly the role played by improvisation from the late Middle Ages through to the time of Shakespeare and beyond. A careful reading of the essays brings with it the awareness that to ignore improvisation is to distort the art in a major way. In light of the present volume, the very concept of "faithful historical re-creation" takes on a much broader and more complex character.
