One of two medieval door-knockers in Brioude, often described in the literatur. I know that in early times, rings were very important. In case a victim of persecution reached the door and and touched the ring, it had escaped from secular jurisdictation (by entering the clerical one). This was the handle to the sanctuary.
So here is a lion, holding the ring. All around the words “ORIOR EXAMINIS VITA(M) DAT SP(IRITUS) ORIS” are engraved. “I am born without life - Breath gives me life”.
“I am the gate; whoever enters through me will be saved.They will come in and go out, and find pasture.”
