Heracles – or Hercules as he has been more popularly known ever since the Roman times – was the greatest of all Greek heroes, “one who surpassed all men of whom memory from the beginning of time has brought down an account.” A half-god of superhuman strength and violent passions, Heracles was the epitome of bravery and masculinity in the ancient world and the most notable champion of the Olympian order, which he staunchly protected from various chthonic monsters and earthly villains. Even though his short temper and lack of composure did cause both him and quite a few innocent mortals undeserved trouble, the magnitude of his labors was of such an order that it earned him the prize of immortality. The protagonist of hundreds of myths – the chronology of which is impossible to figure out – Heracles is undoubtedly one of the most iconic figures in all of Greek mythology.
