Although the picture Mr. Halloway draws on the “bullet” is shortly to be revealed as symbolizing something else, a crescent moon has rich associations.

The word “crescent” comes from the Latin crescere, for “to grow,” so the crescent moon is waxing or increasing -- which is what is happening at this point in the story to Mr. Halloway’s power and stature against the evil circus.

Akkadians, Sumerians, early Turks and Persians used the crescent in their iconography.
