What God has an invisible helmet?

The god you're referring to with an invisible helmet is Hades, the ancient Greek god of the underworld. In Greek mythology, Hades possessed a magical helmet known as the Helm of Darkness (or Cap of Invisibility), which granted its wearer the power to become invisible.

Helm of Darkness (Cap of Invisibility)

• Power: The helmet granted the wearer invisibility, allowing them to move undetected by others. This powerful artifact was often used by Hades when he needed to remain hidden or when he wanted to approach mortals and gods without being seen.

• Mythological Use: In various myths, Hades used the Helm of Darkness to his advantage. For example, during the Titanomachy (the war between the Titans and the Olympian gods), Hades, along with Zeus and Poseidon, used the helm to fight the Titans. In Homer's Iliad, the helmet was also used by Hermes and Perseus in other myths.

• Role in "Perseus and Medusa" Myth: In the myth of Perseus, when he set out to slay Medusa, the Helm of Darkness was given to him by Hades to help him remain undetected while he performed his dangerous mission.

Significance:

• The Helm of Darkness is not just a symbol of power, but also a tool for maintaining control over the unseen and the underworld. Its invisibility aspect has been interpreted as a symbol of the mysterious and often hidden nature of death and the afterlife, which Hades governs.

Other Notable Gods and Invisibility:

• Hermes, the Greek god of travelers, thieves, and messengers, also had the ability to become invisible through the use of his talaria (winged sandals) and helmet, but Hades' helmet is the most iconic when it comes to invisibility.
