TNA's The Final Deletion: 8 Things You Totally Missed
5. Playing The Fiddle As Rome Burns
Matt summons Jeff to the battlefield by playing a violin, an instrument he claimed was given to him by Antonio Stradivari. Ol' Antonio died in 1737, so it is unlikely that there is any truth behind this particularly wild claim. I'm not here to talk about Italian craftsmen though.
In truth, this one is fairly simple. Matt has referred to Jeff as Brother Nero throughout, so his playing a violin as Jeff approaches the battlefield is apt. 'To fiddle while Rome burns' is to engage in seemingly trivial acts as something disastrous approaches, and Matt's playing of the violin is exactly that.
The idiom itself comes from the myth that Roman Emperor Nero played the fiddle as his beloved Rome burned to the ground. Nero, Brother Nero, violin, fiddle.
