Dream of Light (Spanish: El sol del membrillo, lit. "The Sun of the Quince"), also known as The Quince Tree Sun, is a 1992 Spanish narrative/documentary film directed by Victor Erice. The film centers on Spanish painter Antonio López García and his attempt to paint the eponymous quince tree. López struggles to capture a perfect, fleeting moment of beauty on canvas, and the film meticulously chronicles his work.

The film begins by showing Antonio López García as a very meticulous painter. He drives in pegs to mark his stance, hangs a weight and uses strings to determine the symmetry and center of his painting. His first attempt starts out peacefully but he soon encounters problems due to the weather and the size of his canvas. As López and a friend discuss Michelangelo's The Last Judgement, painted when Michelangelo was in his 60s, which López is fast approaching, the film's subject takes shape as the relationship between the artist's work and his own mortality. López's future attempts are much more rushed and frantic as he struggles to compete with the weather, the fleeting sun and the rotting and weighed down fruit in maintaining his vision.
