Roman Fascinata or good-luck/virility amulets, made of cast bronze
and offered on eBay as "found in the Balkans".
This one is somewhat larger, and too heavy to wear around the neck. Perhaps a key-ring ?
A tiny model of an erect penis often contained in a bulla or locket
was worn by Roman boys around their necks in anticipation of their mature virility and its gender-status.
It was called a Fascinum.
This fascinating word also meant a brushwood faggot for lighting fires -from fascis a bundle.
Fasces were the symbol of the Roman Republic
and, taken over by Mussolini, gave the name to Fascism.
A Fascio was any Italian political group or club.
Here is a modern extravagance for contrast and comparison...
...worthy of Salvador Dalí !
