From the museum's description:
Dalí's penchant for optical illusion and veiled iconography are evident in this painting. As seen from a distance, a rendition of Raphael's Sistine Madonna (after 1513; Gemäldegalerie Dresden) is situated within a gargantuan ear-a reference to the Passion of Christ. From close range, it is an abstract work composed of countless particle-like gray and pink dots, reflecting the artist's interest in nuclear physics.
I would not have known about the nuclear physics connection. Or that a gargantuan ear was a reference to the Passion of Christ. Perhaps that will become the name of a new church... "Our Lady of the Gargantuan Ear."
