Where was ballet first discovered?
Ballet was never really 'discovered'. Instead, it grew and
changed from what it was to what we know today.
The predecessor to ballet started during the Renaissance in
Italy. It then migrated to France.
What we consider ballet today, however, really started in France
with Louis the 14th. I'm not going to give you the entire story,
but there's a really excellent history of ballet
