Sword-and-sandal films are a specific class of Italian adventure films that have subjects set in Biblical or classical antiquity, often with plots based more or less loosely on Greco-Roman history or the other contemporary cultures of the time, such as the Egyptians, Assyrians, and Etruscans, as well as medieval times. Not all of the films were fantasy-based by any means. Many of the plots featured actual historical personalities such as Julius Caesar, Cleopatra, and Hannibal, although great liberties were taken with the storylines. Gladiators and slaves rebelling against tyrannical rulers, pirates and swashbucklers were also popular subjects.
