Which seven elements were known in ancient times because they occur naturally in relatively pure forms?

The seven elements known to the ancients because they occur in nature in relatively pure forms are gold, silver, copper, iron, lead, tin, and mercury.1

These substances were recognized long before the modern definition of a chemical element was established, and they are referenced in historical texts such as the Bible and the Caraka-samhita. While ancient philosophers often theorized that all matter was composed of principles like air, earth, fire, and water, these seven metals were physically utilized by ancient civilizations for various ornamental and utilitarian purposes due to their availability in a native or metallic state.123
