The forest glade may symbolize The Garden of Eden, which was once a paradise but which, as a result of man's tendency to evil, lost its innocence and beauty. Later in the novel, the glade too is spoilt by the actions of the children.
Dazzle camouflage, known as Razzle Dazzle or Dazzle painting, was used on ships during World War I and World War II. Originally created by artist Norman Wilkonson, it consisted of a complex pattern of geometric shapes in contrasting colours. Dazzle did not conceal the ship, but it made it harder for the enemy to estimate its type, size, speed, and heading.
Face and body painting has been used around the world for hunting, religious, and military reasons. For example, Native Americans often entered battle naked except for a loin cloth, but with their bodies painted. Face painting was once common in tribes on all continents.
