Italian: faccia di bronzon

faccia di bronzon

Ciao,

Could someone explain why faccia di bronzon refers to a person who is shameless, please?

I know it literally means a face of bronze.

If a person is thin-skinned, s/he is with high self-esteem. If a person's face is of bronze which is very hard, it could refer to someone is shameless. Does this assumption make sense?

Thank you!

English has the same kind of expression: a shameless person is “brazen,” which is an archaic word meaning “made of brass” (brass like bronze is an alloy based on copper).

Regarding the English word

The figurative sense of "hardened in effrontery" is from 1570s (in brazen-faced), perhaps suggesting a face unable to show shame.
