When Dawn, Noon, Sunset, and Twilight was shown in an exhibition at the Guggenheim Museum in New York, it was accompanied by this sound track: "What time is it? It is the hour of the Angelus. Well then, waiter bring me a harlequin!" The work was completed in 1978 and shows Dalí was still interested in stereoscopic painting. The painting of the woman and landscape is covered with colored dots. The shades of the colors vary to give the suggestion of the different light that can be seen at dawn or at noon. Color was becoming increasingly important to Dalí in his work; through the use of contrasting segments of color, distanced equally, he was attempting to create vibrations between the colors, thus enhancing the autonomy of the stereoscopic space within the piece.
    The repeated image of the woman is taken from Millet's The Angelus, a work that Dalí incorporated into paintings in the Thirties, one of which was The Angelus of Gala. The "Angelus" would often appear in the background of Dalí's paintings. Only the woman is seen, as if she has finally submerged the male that Dalí always saw her as the predator of.
