Final answer:
Pablo Picasso, a pioneer of Cubism, ignored traditional perspective in his art to present multiple viewpoints at once, while Salvador Dali applied perspective differently in his Surrealist works. Thus, it's not accurate to say both ignored perspective.
Step-by-step explanation:
The question pertains to whether Pablo Picasso and Salvador Dali ignored the concept of perspective in their artwork. Pablo Picasso, known for co-founding the Cubist movement, revolutionized the representation of space in his paintings. His approach diverged from conventional perspectives, such as linear perspective upheld since the Renaissance. In Cubism, as developed by Picasso and Georges Braque, different viewpoints, light sources, and planar constructs were incorporated into a single composition, deliberately ignoring classical perspective to emphasize the flatness of the picture plane. This style allowed for multiple perspectives simultaneously and redefined the experience of three-dimensionality. Therefore, Salvador Dali, who had a different approach with surrealistic elements, did not ignore perspective in the same way Picasso did with Cubism. Considering these art historical facts, the correct answer should be that either Picasso or Dali ignored perspective, but not both.
