I'm Joana, a portuguese restorer and art historian. I'm currently working on a beautiful 17th century crucifix covered in engraved mother-of-pearl. The base was broken in half and the entire piece is missing pieces of mother-of-pearl, which I'm now adding back.
As you can see, I'm missing half of this symbol. I can't, for the life of me, remember the name of said symbol, nor how it looks completed.
Could any of you please tell me its name or give a link of a complete image of this symbol, so I'll know what to engrave?
Thanks in advance,
Edit: Can it be a symbol for Auspice Maria?
