I tre centurioni / Three Swords for Rome (1964)

During the reign of the emperor Elagabalus, the commander of the Roman legions in Asia, Marcus Gaius, is forced for economic reasons to dismiss the mercenaries. Three dismissed centurions, Fabius, Maximus, and Julius take refuge in the city of Messe, where Adakir is king and whose second wife Siride plans to occupy the throne in place of the legitimate heir, the princess Elena. After various adventures the three centurions end up in prison, but at the behest of Siride, the king grants them freedom and they become instructors to the palace guards. The Persian ruler Artaxerxes arrives and tries to place himself at the head of a revolt to dominate unchallenged. Siride and Atenofane, his counselor, with the complicity of Artaxerxes, seek to implement an evil plan for the conquest of power, but the three centurions attempt to foil their plan.
