Sunday Dalí: Enchanted Beach with Three Fluid Graces, 1938. Oil on canvas, 25 ⅝ x 32 inches. The Salvador Dalí Museum, St. Petersburg, Florida.

From the Dalí museum:

This title refers to the Greek myth of the three Graces who represent beauty, charm, and joy. Yet, the inclusion of the rod and string suggests another Greek myth — the Three Fates. Known as the Moirae, the Three Fates control the thread of life of every mortal from birth through death. The Fate on the right holds a long spindle to weave the thread of life, the central Fate measures the life span, and the Fate on the left decides one’s death by cutting the thread.
