For three days Juno sat fuming, still trapped in Vulcan's chair, she could not sleep, she could not stretch, she could not eat. It was Jupiter who finally saved the day, he promised that if Vulcan released Juno he would give him a wife, Venus the goddess of love and beauty. Vulcan agreed and married Venus. He later built a smithy under Mount Etna on the island of Sicily. It was said that whenever Venus is unfaithful, Vulcan grows angry and beats the red-hot metal with such a force that sparks and smoke rise up from the top of the mountain, to create a volcanic eruption.
