Historical definition

Rillus is an instrument used by goldsmiths to pour their melted metals into long forms; it is called an ingot.

Meaning

The sentence begins by naming an instrument, then connects it with pouring molten metal into a long form. Its final English equivalent is preserved because it belongs to the witness, even though the relation between the instrument and the resulting ingot can be easy to blur.

Use in the book

The process described is casting, rather than the earlier stages of finding an ore or separating its metallic portion. Compare Regulus for the purified metallic material.

In this edition

Ingot modernises the historical spelling Jngat. The explanation follows the complete sentence and does not silently replace its instrument with a finished bar.
