Ceyx and Alcyone were both of royal blood.These two loved each other devotedly and never wanted to be apart. They even called each other "Zeus" and "Hera."
Alcyone and Ceyx
Ceyx decided to leave and make a journey across the sea to consult an oracle. Alcyone asked to go with him because she knew of the power of the sea, but Ceyx told her no.
Zeus was upset at Ceyx and Alcyone because they called themselves "Zeus" and "Hera". He was so angry that he cast a lightning bolt down on Ceyx's ship, which caused it to sink.
Alcyone prayed to Hera for Ceyx. Hera told her messenger, Iris, to go to the house of The God of Sleep and ask him to send a dream to Alcyone that Ceyx had died. The God of Sleep sent Morpheus to do the job.
NO, you couldn't have possibly died!
Alcyone headed back to the water. She found her husband laying in the water, dead. As she ran towards him, she suddenly got wings and started to fly.
Out of compassion, the gods reunited them as two birds. When Alcyone broods over her floating nest, her father calms the winds and Zeus calms the sea for her. Once the eggs hatch, the charm is broken.
