I thought Homans mentioned that ballet had come from Italy, but I'm out of the country and geoblocked. Hola is impossible slow, and I can't confirm.
How much do we know about what was brought from Italy? The La Scala school was founded in the early 19th century: was there a continuity in Italy, or was ballet brought back to Italy from France, and the Italian influence -- dancers, technique, emphasis -- that influenced French and Russian ballet in the 19th century a circular influence?
