In this article, we'll discuss the superstitions associated with metals and their elemental properties. Since ancient times, cultures worldwide have attributed mystical powers to metals like silver, iron, gold, and copper, believing that their chemical and physical characteristics—such as corrosion resistance, luster, or conductivity—endowed them with protective, healing, or spiritual qualities.

We'll focus on how the intrinsic properties of these metals, rather than the specific shapes of the objects made from them, inspired beliefs that have endured across generations.

Imagine each metal as a character with a unique aura: some are guardians against evil, others are healers, and all have stories to tell.

Silver, with its bright luster and resistance to ordinary oxidation, has been revered in many cultures as a metal with protective and purifying properties. Its ability to maintain its shine without corroding, unlike rapidly oxidizing iron, made it seem almost magical in antiquity.

Chemically, silver has a relatively high electronegativity, making it less reactive to oxygen under normal conditions, granting it an appearance of "eternal purity." This quality led many cultures to associate it with moonlight and divinity.

• In European folklore, especially in myths about werewolves, silver was believed to repel or destroy supernatural creatures. This belief possibly stems from its corrosion resistance, seen as a sign of purity that counteracted dark forces.

• In Greek mythology, silver was linked to Artemis, the goddess of the moon, reinforcing its connection to the sacred.

• In Latin America, Indigenous cultures like the Incas valued silver not just for its beauty but because its unalterable brilliance seemed to channel spiritual energies.

From a metallurgical perspective, its high electrical and thermal conductivity may also have inspired these beliefs, as ancient people noticed that silver "responded" to human touch uniquely, as if it had a life of its own.

Iron, with its robustness and abundance, has been a symbol of strength and protection in countless cultures, often viewed as an amulet against malignant spirits.

Unlike silver, iron is prone to oxidation, forming rust when exposed to water and oxygen. However, this very chemical reactivity may have endowed it with a protective aura.

• In medieval Europe, it was believed that iron, especially when cold-forged, could repel fairies, demons, and witches. This superstition likely relates to its hardness and toughness (simple forms have 400−800 MPa tensile strength), which made it ideal for tools and weapons, symbolizing the human capacity to dominate nature.

• In African cultures like the Yoruba, iron was associated with Ogun, the god of war and metals, and was used in rituals to protect homes and communities.

• The idea that iron "absorbs" or "neutralizes" evil energy might derive from its ability to become magnetized—a property the ancients didn't scientifically understand but perceived as mystical.

Iron's role as a reliable material for physical structures extended its symbolism as a barrier against the intangible.

Gold, with its eternal luster and chemical inertia, has been revered as a divine metal in cultures worldwide. Its resistance to oxidation—it doesn't react with oxygen or most acids—made it appear immortal, a reflection of the gods or the sun itself.

Metallurgically, this stability is due to its high electronegativity and electron configuration, which makes it almost inert, requiring extreme compounds like aqua regia to dissolve it.

• In Ancient Egypt, gold was associated with Ra, the sun god, and was believed to grant spiritual protection and connection to the eternal. Pharaohs wore it not only for value but because its incorruptibility seemed to guarantee immortality.

• In India, gold is central to Hindu rituals, where it is considered a purifier that attracts divine blessings, possibly due to its malleability, which allows it to be molded into sacred shapes without losing its essence.

• In medieval alchemy, gold was the final goal, not just for wealth, but because its resistance to degradation symbolized spiritual perfection.

Scientifically, its high electrical and thermal conductivity may have reinforced these beliefs, as gold "responds" to the environment uniquely, as if possessing intrinsic power.

Copper, with its reddish tone and high conductivity, has been associated with healing properties in many cultures.

Metallurgically, copper is ductile and malleable, making it easily workable, and it forms a green patina (copper carbonate) upon oxidation, which acts as a protective barrier. This patina, visible on ancient statues, may have inspired the belief that copper has a regenerative power.

• In Ayurvedic medicine in India, copper was used to store water, believing its antibacterial properties purified the liquid. Modern studies confirm copper has antimicrobial effects, suggesting these superstitions had an unrecognized scientific basis in their time.

• In Ancient Egypt, copper was associated with Hathor, goddess of love and healing, and was used in rituals to promote health.

• In Mesoamerican cultures like the Aztecs, copper was considered a conductor of vital energy, perhaps due to its ability to conduct electricity, a property ancient people perceived intuitively through its warmth to the touch.

This connection to vitality led copper to be seen as a metal that could heal both body and spirit.

From a scientific perspective, superstitions about metals are deeply tied to their elemental properties:

• Corrosion Resistance (Silver, Gold): Suggested purity and a connection to the divine or immortal, as they remained unchanged by earthly elements.

• Reactivity (Iron, Copper): These metals, which change over time (rusting or forming patina), could be interpreted as interacting with supernatural forces or undergoing a protective sacrifice.

• Conductivity (Gold, Silver, Copper): Their ability to quickly transfer heat or electricity might have been perceived as a capacity to channel energy (spiritual, healing, or vital) by the ancients.

• Tenacity/Hardness (Iron): Its ability to withstand great physical loads made it a natural symbol of barrier and protection against invisible threats.

What the ancients saw as mystical powers—the incorruptibility of gold, the protection of iron—we now explain with chemistry and physics, but both perspectives highly value the unique properties of these elements. These beliefs not only reflect human observation but also show how metallurgy has been intertwined with culture, shaping rituals and traditions for millennia.

The superstitions about metals remind us that science and culture are more connected than we often realize. What the ancients perceived as mystical powers—the incorruptibility of gold, the protection of iron—we now explain with chemistry and physics, yet both perspectives fundamentally value the unique properties of these metals.
