I suspect the reference to "Letter to Syracuse" has more to do with the ancient capital of Sicily and a classic correspondence than anything else, and probably one which complains about the unending wars of the period. Maybe it's a letter by philosopher Annaeus Seneca (4 B.C. to 65 A.D.). But then Seneca was exiled to Corsica, not Sicily. Well, they're both islands. Maybe the songwriter got confused. If he only had access to Goggle Earth!

Cheerily,
