Then Iris, who could see beyond and through the darkness, had a vision of the beautiful Queen Halcyone, of Sicily, who mourned her shipwrecked husband, the captain of this ship.
Without a moment's hesitation, Iris set out for the palace of Somnus, the king of sleep. It was a long and dangerous journey. Even Apollo did not dare to approach it at dawn, noon, or evening. It was set in a country where the light glimmered but faintly, and clouds and shadows rose out of the ground. No wild beast, or cattle, or tree moved by the wind, or any sound of voices broke the stillness, but the river Lethe flowed through it, rippling with a low kind of lullaby.
Iris approached the home of Somnus very timidly. All the way there were fields of poppies and the herbs from which Night distilled sleep to scatter over the darkened earth. There was no gate to the palace to creak as it opened, or any watchman. So this little errand girl of the gods went inside and made her way to the room where there was a throne of black ebony draped with dusky plumes and curtains. On the throne reclined Somnus, scarcely opening his eyes, and with his hair and beard covering him like a mantle.
Iris knelt before him,
"Somnus, gentlest of the gods, and soother of careworn hearts," she said, "will you not allow me to despatch a dream to Halcyone about her husband whom she mourns. See these dreams that lie around you, as many as the harvest bears stalks, or the forest leaves, or the seashore grains of sand! Can you not spare one beautiful dream for Halcyone?"
Somnus called his servant, Morpheus, who selected a dream and flew, making no noise with his wings, until he came to the city of Trachine where Halcyone could not sleep, but lay and tossed and wept in terror at the thought of what might have happened to her husband's ship. And at that moment Halcyone fell into a deep and happy dream in which she saw her husband. He stood beside her couch and spoke to her.
"The stormy winds have sunk my ship in the Aegean Sea," he told Halcyone, "let me not be alone. Arise and come with me!"
It was the most enlightening dream that Somnus could have sent. Halcyone left off her lamentations and implored the gods that she be allowed to join her husband, and the pitying gods turned them both into birds. They became the Halcyone gulls of the sea, riding the surf together, guarding their nest that floated upon the sea, and never again separated.
As soon as she felt sure that her errand was safely accomplished, Iris made haste to leave the domain of Somnus, for she felt its drowsiness creeping over her. She tried not to crush any of the sleep producing herbs as she went, and she was careful not to pick a single poppy. At last she was safely outside the boundaries, and then she could hardly believe what she saw, for a wonder had happened to her.
The gods had built her a long bridge that arched from the earth to the sky and over which she could go home to Olympus. It was made of colored stones, the ruby, the topaz, the emerald, the sapphire, and the amethyst. Row upon row the glistening stones of the arch made a bright path for Iris' feet. She passed along it, the light of the brilliant gems scintillating about her, and when she came to the abode of the gods, Iris found another surprise. There was a beautiful new dress waiting for her there.
