Doesn't get any more musically orgasmic: Respighi's The Pines of the Appian Way - from the Pines of Rome (movement 4). There's a story. Rome. It's legion. Picture this:
"The sun is just coming up; the carts and wagons of the farmers are leaving the city and returning to the latifundia; tramping up the road and into the city come the lead cohorts of the legion; behind them, all the way from Rome to Capua, hang the 6000 survivors of Sparticus' slave army, slowly dieing on their crosses as the triumphant legion of Crassus enters the city and ascends the Capitoline. The Servile War is over! Ave Imperator!"
