When Hephaestus found out his mother Hera had rejected him on his birth, he got very embittered and promised to take revenge on her. So he decided to create a magic, golden throne and send it to Mount Olympus as a special gift to his mother.
When Hera saw the splendid throne, she immediately got enthused over it and, without thinking, she cheerfully sat on it. All at once, invisible, unbreakable chains appeared and tied her up rapidly. Hera cried for help and all Olympian gods ran for support, but none of them was capable of relieving her; soon they realized that the only one who could liberate Hera was Hephaestus himself.
The gods therefore asked from Dionysus, the god of wine, to offer sweet wine to Hephaestus and intoxicate him. So Dionysus did, and this way he managed to bring Hephaestus up to Mount Olympus and free Hera from her burdens. After that, the gods thanked Hephaestus by giving him Aphrodite, the goddess of love, as his wife and created a marvellous palace for him on Mount Olympus.
