Greek and Roman Mythology are not all that different from each other, all of the gods are similar, only difference in between them are their names. Also many of the stories are exactly the same, such as the story of Eros and Psyche in greek mythology, the roman version of the story is called Cupid and Psyche, exact same story but different names. Also in these myths there are many different Major and Minor gods who seem to be constantly in conflict with each other. There are demi-gods, these are the children of the gods who have had mixings with humans, many of the demi-gods are well known heros in mythology.
