How did Hera tricked Zeus?

Hera first makes an excuse to leave her divine husband Zeus; in her deception speech she declares that she wishes to go to Oceanus "origin of the gods" and Tethys, the "mother". Instead Hera beautifies herself in preparation for seducing Zeus, obtaining the help of Aphrodite. In the climax of the episode, Zeus and Hera make love hidden within a golden cloud on the summit of Mount Ida. By distracting Zeus, Hera makes it possible for the Greeks to regain the upper hand in the Trojan War.
