Letters are a symbol of deception, but also of love. For Cyrano, letters are an odd opportunity both to hide his identity and openly reveal his emotions. Notice that the difficulties and complications begin when Cyrano has to move out of the realm of letters and into speech – in the balcony scene with Roxane. This is where he’s almost caught, when he can no longer hide behind the letters. However, it is also where we see his true emotion most clearly. Of course, it is fitting that Roxane discovers the truth in the final scene when she watches Cyrano reading his letter aloud; this is the ultimate combination of the written and spoken word, and even in the dark Cyrano can no longer hide behind paper.
