Historical Definition

Aurum planatum is what they call leaf gold, or hammered gold.

Meaning

The definition emphasizes a physical form created by working the metal. It does not describe a philosophical gold, a liquid medicine or an ore. The phrase “leaf gold” provides the principal recognition clue, and “hammered” records how its form is understood.

This is a useful anchor beside the dictionary’s more elaborate Aurum terms. A passage about planatum begins with a materially specified form rather than automatically invoking every philosophical meaning of gold. Any later transformation belongs to the described operation, not to the headword alone.
