What furniture style features gilt and metal acanthus leaves, laurel leaves, and winged victories?

The Empire furniture style is characterized by its grandiosity and details reflecting classical influences, particularly from ancient Greece and Rome. Elements like gilt and metal acanthus leaves, laurel leaves, and winged victories are significant in this style, symbolizing triumph and valor, which were prominently featured in furniture and decorative arts during the early 19th century. This style often portrays a sense of power and elegance, drawing inspiration from Napoleon's rule, where such motifs became widespread.

The other styles listed do not emphasize these specific ornamental features as prominently as the Empire style. Louis XIV, while opulent, focuses more on elegance rather than the military and classical iconography specific to Empire. Colonial furniture tends to emphasize practicality and simplicity over ornate detailing, and Victorian style, although decorative, has its unique motifs that often focus on ornateness linked to nature and the Industrial Revolution rather than classical themes. Thus, the inclusion of these specific design elements firmly establishes Empire as the correct answer.
