Step-by-step explanation:
The discovery of perspective during the Italian Renaissance was significant because it revolutionized art by creating a realistic depth perception. Artists used the technique of linear perspective, which involved using receding parallel lines to create the illusion of three-dimensional space on a flat surface. This innovation in art allowed painters to move away from the flat and static style of the Gothic period and create more lifelike representations of nature and the human form.
Artists like Leonardo Da Vinci, Michelangelo, and Titian embraced the use of perspective in their paintings, contributing to the vibrant culture of realism in Renaissance art. The development of perspective was part of a wider trend towards realism in the arts during this time period.
