What are the motifs in Marie Antoinette: The Journey by Antonia Fraser?

Coming of age is a motif in the book. The book follows Antoinette from her birth to her death. She is little more than a child when she is promised to Louis, heir to the throne of France. Antoinette matures physically, as is natural and necessary. This aging is noted in several ways, including the fact that she begins her period and comes of an age to have children. Antoinette is very young upon her marriage and has little interest in either the affairs of the country nor of the political wrangling and intrigues common to the time and place.
