The basis for the new Peacock television series: The classic, in-depth account of the ancient Romans’ obsession with the bloody and brutal gladiatorial games.

“If you can imagine a superior American sports writer suddenly being transported back in time to cover the ancient Roman games, you will have some idea of the flavor and zest of [Those About to Die],” said the Los Angeles Times about Daniel P. Mannix’s century-by-century—and nearly moment-by-moment—narrative of the Roman Empire’s national institution. Putting the games in the context of Rome’s rise and dramatic fall, Mannix captures all the history, planning, and savage pageantry that went into creating the first spectator sports.

The games began in 238 BC as nearly county fair–like entertainment, with trick riding, acrobats, trained animals, chariot racing, and athletic events. The contests then evolved into slave fights thanks to wealthy patricians Marcus and Decimus Brutus, who wanted to give their father an unforgettable funeral by reviving an old tradition. What the brothers wrought, Rome devoured, demanding even greater violence to satisfy the bloodlust of the crowd. Architectural wonders in themselves, massive arenas like Circus Maximus and the Colosseum were built, able to host sea battle reenactments on actual water. Successful gladiators found fame, fortune—and freedom.

But as Rome begin to fall in the fifth century, so did the games, devolving into nothing more than pointless massacres. In the end, millions of humans and animals were sacrificed in barbaric displays. What were once ceremonies given in honor of gods met an inglorious fate, yet they still captivate the imagination of people today.
