@bolino,
I think that farmerman is referring to a famous fictional Belgian Detective.
The reason I mentioned Monaco is because they found a big shrine to Hercules there, and I remember the experts thinking that the Greeks had landed there in the dim and distant past, and their influence was still around when the Romans came to stay. Romams used to incorporate any and every god they came across, and would have had their own temples to Hercules, to add to all the other gods they worshipped.
I think they were playing safe,
