Mythical monsters and creatures were invented to be used in folklore, enforce social taboos, as well as entertain and frighten audiences. We invent mythical monsters through dreams and these mythical monsters become the manifestation and physical representation of the unknown and beings that are out of our control.
A Hero in Greek mythology is the man or woman who has more strength, courage, and special skills than the average person. They also stand out for their ingenuity, intelligence, and charisma. A Greek mythology hero often has divine ancestry and is regarded highly by others for their superhuman actions.
The monsters that Hercules defeated include the Nemean lion, Lernaean Hydra, Ceryneian Hind, and Erymanthian Boar. The other monsters that Hercules defeated were the Stymphalian birds, the Cretan bull, the mares of Diomedes, Geryon, and Cerberus. The defeat of all these monsters made up the 12 Labors of Hercules.
