Athena helped Medusa by transforming her into a "monster"

The argument

Most writers credit Athena with laying a curse on Medusa, and that reading has hardened into the standard one. However, it could also be the case that Athena was not trying to curse Medusa at all, but instead to help her. The case begins with the relationship between the two figures. Athena is a virgin goddess, and she was the patron of Medusa. When Poseidon raped Medusa, she called out to Athena for both forgiveness and guidance. Nothing in that sequence is a transgression on Medusa's part: she is the one who was wronged, and in the aftermath she turns toward her patron rather than against her. Here is where interpretations differ. Athena's decision to curse Medusa with her petrifying stare would not make sense if Medusa was the victim of rape — a curse is a response to an offence, and on this reading Medusa had committed none. The interpretation that fits the facts better is that transforming Medusa was not an act of rage; rather, it was an act of protection. Athena's position was constrained, because she could not punish Poseidon for what he did to Medusa. What remained available to her was to act on behalf of the one who had been harmed, and so the goddess did the only thing she could do, which was to protect her former priestess. Read that way, the transformation changes character entirely. Giving Medusa the ability to turn people to stone becomes a mechanism of self-defence rather than a punishment or a mark of monstrosity, because of what it makes impossible: it grants Medusa the power never to feel helpless again when faced with similar situations, since anyone approaching her with harm in mind is stopped before reaching her. If that is right, the familiar categories fail to describe her. She is not a villain, since the power she wields was conferred for her own protection; and she is not simply a victim either, since what she was left with was the means never to be made one again.

Premises

Counter-arguments

While it would seem much more rational that Athena was blessing rather than cursing Medusa, it is also possible that Athena cursed Medusa out of jealousy. Even though Medusa sought Athena's counsel, there is still a case for Athena being angry towards Medusa. One of the things that could have fed this anger was jealousy. Medusa originally promised herself to Athena, but her promise to Athena came undone when Poseidon raped her. One of the staples of being an Olympian god's mate was that once claimed, they were bound to be mates forever. Athena could have arguably felt betrayed by Medusa since Poseidon claimed her, even though Medusa promised herself to Athena. In turn, the virgin goddess would feel inclined to lash out in anger against Medusa for this development.

Rejecting the premises

[Rejecting P1] The premise builds on one strand of a myth surviving in several incompatible versions: Medusa's priesthood and her appeal to Athena appear in some retellings and not in the earliest sources, so this is a choice of source rather than an established fact. [Rejecting P2] The inference assumes a Greek deity would act only reasonably. The myths are full of gods punishing mortals for what was done to them, and the pollution of a temple was itself an offence regardless of fault, so a curse is not the incoherence the premise treats it as. [Rejecting P3] Even granting a protective intent, the outcome is not the conclusion: Medusa is exiled, feared and finally beheaded, which is how the victim reading in this debate describes her — so a transformation meant kindly would not show she was neither victim nor villain.
