Final answer:
The primary function of the Hall of Mirrors in the Palace at Versailles was to emphasize King Louis XIV's importance and serve as a magnificent backdrop for hosting events and demonstrating the monarchy's power. The correct option is 1.
Step-by-step explanation:
The main function of the Hall of Mirrors in the Palace at Versailles was to emphasize the importance and power of King Louis XIV. It symbolized the majesty of French monarchy, where every aspect of the king's life was presented with regal ceremony. The opulent gallery, with its series of 17 mirrored arches and elaborate paintings, also served as a grandiose setting for hosting lavish parties and formal events like military agreements.
Thus, the second option, 'To host parties and military agreements,' accurately explains one of the Hall of Mirrors' multifaceted roles, but its function to underscore the king's significance is the primary purpose, aligning with the first option.
Beyond serving as a place for entertainment, which included ballets, balls, hunts, and receptions, the design of the Hall of Mirrors and the entire Palace of Versailles was intended to glorify the power and achievements of the Sun King. The interior design, known as Louis XIV style, featured heavy gilded plaster moldings, marble pilasters, and bronze symbols of France, all of which conveyed the grandeur and greatness of the Sun King's reign.
