1. Cyrano references to things like a hot air balloon and a rocket ship. A hot air balloon is spherical object that to fly they shoot fire into to make hot air in the inside of the balloon to make it go up. A rocket is a cylindrical object with an engine that fires to make it rise.

2. The moon probably represents dreamers. The people he mentions affected the way the world works and were ridiculed and punished by other people. They were in front of the movements and they were dares. It reveals that Cyrano dares to do the things he does and wants to reach those heights.

3. The plum represents a freedom from everything, individuality, and bravery.

4. Falling leaves and darkness represents approaching death and falling ideas.

5. The love between Cyrano and Roxanne is a intellectual love but something Cyrano cannot reach. The love between Christian and Roxanne is more of a physical love. The love between De Guiche and Roxanne is purely sexual; all De Guiche wants from Roxanne is for her to be his mistress.
