The metals of antiquity are the seven metals which humans had identified and found use for in prehistoric times. These elements, gold, silver, copper, tin, lead, iron, and mercury, are the metals from which the modern world was forged. Until the discovery of arsenic in the 13th century, these were the only known elemental metals, compared to the 86 known today.
The metals of antiquity generally have low melting points, with iron being the obvious exception.

Each of the metals was associated with one of the seven then-known celestial bodies, and one of the seven days of the week.
