rulers will be appointed who have lost the guardian power of testing the metal of your different races, which, like Hesiod's, are of gold and silver and brass and iron. And so iron will be mingled with silver, and brass with gold, and hence there will arise dissimilarity and inequality and irregularity
Plato treats brass as one stratum in a psycho-political metallurgy of souls whose improper mixture produces civic discord, making it a marker of constitutional degeneration.

Kerényi, Karl, The Gods of the Greeks, 1951supporting
iron and brass and all metals were jumbled together and had disappeared in the chaos; nor was there any possibility of extracting ore from them; and they had scarcely any means of felling timber.
In the Laws, Plato envisions a primordial catastrophe in which brass and iron collapse into undifferentiated chaos, requiring the gradual re-emergence of metallurgical arts as a precondition for civilization.
Whatever her partner required of her, she rendered and fulfilled with brass and with gold, as fully as he wished.
Campbell's citation of Gottfried's Tristan uses brass alongside gold as a formulaic phrase denoting full and complete fulfillment, preserving a residual connotation of brass as a lesser but still valued metal in an erotic-sacrificial context.
