Could this be figurative, as in somone who hides their value or does not advertise their true abilities?
Yes, it could.
Thank you. I had unsavoury visions of a slave in the market.
Hide it from who, the drunk parrots
under a bushel?
This is sentence is kind of vague. Could someone explain exactly what this means?
Now what could that mean ? "You hide your price ?" What did the Romans mean when they said so ?
Maybe it was a slave trying to avoid being bought?
It doesn't really make any sense; it's not like slaves had tags with their price glued onto their bodies like a can of soup at a supermarket in the 1980s. If you wanted to know a slave's price, you'd ask the merchant (and probably haggle).
First thing I thought of
