Asterix the Gladiator (Asterix, #4)

Oh no! The Romans have captured Cacofonix the bard as a gift for Caesar—and the highly unimpressed Emperor plans to throw him to the lions. By the time the other Gauls notice how quiet and peaceful the village is, Cacofonix is on his way to Rome. But Asterix and Obelix are hot on his heels and there’s only one way for them to rescue their bard: they have to become gladiators themselves.
