The metals we call noble won’t combine with other elements,
don’t interact with water, air. Of course that means they don’t corrode
or fade or rust, need little work of polishing. So gold and some
alloys and also platinum, like minerals of Elysium,
remain aloof and scintillant, keep their immunity to change
while ordinary iron will burn in time, get eaten by the air
like living things that die and rot and mingle with the fecund mold.
But platinum, its alloys, gold, and all their noble kin, will hold
their purity like some ideal of beauty, bright and sterile,
like everything immortal.
