Herakles (Ancient Greek: Ἡρακλῆς, "Hēraklēs" - “one glorified of Hera”) is a divine hero in Greek mythology. The greatest of the Greek heroes, Herakles was a demigod, son of Zeus and the mortal Alkmene as well as the twin brother of Iphicles. As a god, Herakles served as a paragon of masculinity, and was a patron of heroic endeavor. In Ancient Rome and the modern West, he is known as Hercules, with whom the later Roman emperors, in particular Commodus and Maximian, often identified themselves. The figure is most well known for his famous Twelve Labors, a series of seemingly impossible tasks he was made to complete in order to atone for the crime of murdering his family. As a culture hero, he was said to have started the Ancient Olympic Games and marked out the length of the Olympic stadium. He was the subject of much ancient and modern art, and remains a popular figure in modern times, being the subject of various films and television series, such as Walt Disney's "Hercules".
