Final answer:
The gathered crowd's reactions to the unfolding spectacles before Arthur are diverse, including concern, dark amusement, excitement, fear, and expectancy depending on the nature of the spectacle they witness.
Step-by-step explanation:
The gathered crowd's reaction to the series of spectacles before Arthur ranges from awe to excitement. Initial scenarios depict a mixed reaction of concern and curiosity, as observed in the example of the sick man being taken to the hospital and the policemen navigating the crowd. This shifts to a sense of dark amusement and welcoming as fiend worshippers flash a 'smile of welcome' amid a visual spectacle of flame.
Further descriptions showcase the crowd's engagement with various performances, underlying a multifaceted spectacle unfolding. Another notable reaction is the excitement and expectancy from Jane Withersteen while observing Wrangle, the giant sorrel horse. Elements of fear and concern also thread through some narratives, as revealed by surreal experiences and near-death or intense moments.
Through these excerpts, it is clear that the crowd is a vital component of the narrative environment, with their reactions both shaping and reflecting the unfolding drama. They serve as a barometer of the events and the emotions they elicit, which can range from humor and excitement to suspense and terror.
