When was the first Hot Air Balloon invented and first used for entertainment?

I watched a Movie today called,"The Count of Monte Cristo". There is a scene where the Count came down in one(hot air balloon). I thought to myself,"that's not Historically accurate because there were no balloons during that time period." Am I wrong? A terrific Movie by the way.

orcouldit be triangle,or square shaped for instance

How does a hot air balloon float?

For a science assignment, i would just like to know the basic princple behind hot air balloon flight :)
