There's a verb забронзоветь in Russian formed from word "bronze" with the following meanings when applied to a person:
- to get a shade of bronze (like become a hero to become worthy of a bronze monument)
- to stop self-educating, progressing intellectually
- to become an idol, with shade of losing the actuality, freshness, start moving into past
Maybe English has sort of common and accepted word for this?
Note: I am looking for a term to be applied to a great, known person, like politician, philosopher or other researcher, added to all the meaning.
