Nice! Can you allow 'Innocenzo' for Innocent? Also, I tried thinking of an X answer but couldn't come up with one that convinced me. X does mean a draw in football betting (whereas 1 means home win, 2 means away win - see https://it.wikipedia.org/wiki/Totocalcio) and perhaps X can be the start of a year in Roman numerals - for example in 1937 lira coins you can read 'XV' (see http://numismatica-italiana.lamoneta.it/moneta/W-VE3/22). But I'm not sure these ideas are any good.
The cult of Hercules was a huge part of Roman religion. It was ripped off wholesale from the Greeks (or more likely was part of a wider Mediterranean religion which was carried around by the various peoples migrating around the area), but Hercules was definitely a Roman thing.
Heracles/Hercules was originally a Greek myth, though it did indeed spread throughout the Mediterranean, largely thanks to the Greeks colonising large parts of it, and also Alexander's conquest of Persia helped to spread Heracles' cult out into the east and Egypt
Hercules had a number of myths that were distinctly Roman. One of these is Hercules' defeat of Cacus, who was terrorizing the countryside of Rome. The hero was associated with the Aventine Hill through his son Aventinus. Mark Antony considered him a personal patron god, as did the emperor Commodus. Hercules received various forms of religious veneration, including as a deity concerned with children and childbirth, in part because of myths about his precocious infancy, and in part because he fathered countless children. Roman brides wore a special belt tied with the "knot of Hercules", which was supposed to be hard to untie.
Gosh, Hercules is merely a transliteration of the Greek version. The myth (not "the legend") was Greek, not Roman. And Pantheon wasn't built in 126 A.D. Definitely guys, let Italians make quiz about Italy
Can I suggest that the clue for Pantheon should read "rebuilt in 126 AD" since it was a Hadrianic reconstruction. The original building was built by Agrippa. Hadrian himself preserved the original inscription and no-one knew it was a rebuild until refurbishment works led to bricks with stamps of builders from Hadrian's time being discovered.
It didn't stop me getting it right. But I agree, there are plenty of other Bs that could be considered. Examples: Berlusconi, Brescia, Borlotti beans, Bologna, Bari, Bergamo, Bresaola, Begnini, Boticelli, Barolo etc etc. Italian history and culture is so rich that the list of possibilities is very long.
Cosa Nostra is specifically the "mafia" organization in Sicily, it's not a general term for Mafia.
Fun quiz!
