It is said, that for each artist, at least once in a lifetime, a representation of Christ cannot be missed within the collection, regardless of personal views on the religious matter itself. I dare to add, in that essential gallery, that a vision of Medea is also mandatory, as her myth perfectly shows the issue on moral duality on us, human beings, and depending on the final view of the artist, we can, most likely, be able to see beyond the veil and discover true beliefs and moral opinions. Medea suffers, brings back suffering to others, just to end up getting it back, once more... over and over, during her endless odyssey that, most ironically, finishes on the Elysium, probably because the intervention of her grandfather Helios, the very god of the Sun. Medea is battered and betrayed, an empowered survivor that in the end is forgiven regardless of her countless crimes.
Only in Elysium, Medea will have enough time and maturity to look in retrospective, with pride upon the suffered, and with stoic remorse for the faults. There, striped form her earthly condition, she will just be able to confront eternity in company of beautiful but poisonous jellyfishes, in memory of the two sons murdered by her own hands (according to most sources), that will just show the irony and duality of her own story.
This inherent duality on Medea just dramatizes in the extreme the case of duality in us, human beings, morally and emotionally, everyday, for our lifetimes. Human beings are not absolute: we are mutating polyhedrons in function of different contexts. Who couldn't, if given the case, end up becoming a Medea?
