This is an ancient Roman amulet for luck. Yes those are flying penises.
Also of note, the Roman god of marriage, Mutunus Tutunus, whose name is derived from two Latin slang words for penis. His name is essentially Dick Wiener. If you have ever wondered just how much like us the Romans were, read the etymology section.
It’s a flying fuck.

LITERALLY. A FLYING FUCK.
For the record, the Roman sense of humor was pretty much exactly like the modern American one, only plus magic. Fascina (the name for the flying penises) had the power to drive off evil spirits because they provoked whomever saw them to laugh, and as we all know, evil spirits hate happiness and were supposed to be dispersed by it.
