Pierre,
This is a damaged example of an animal
head "swastika"
fibula.
Two of the arms are almost
complete - I think there is some damage to the animal's ears and snout. The other two arms are broken off. The ring marks in the heads are the animal's eyes. It is often descrobed as horse's heads but I am not sure if that is what they actually are or not.
I will try to look up more information but they are
Roman, I think around 2nd century AD (you can see that yours was pin-back not spring-back). They are often found in the Balkans.
