“Hail, dear children, whoever you are. I will tell you my story; for it is appropriate that I should tell you truly what you ask. Doso is my name, for my stately mother gave it to me.
This passage which describes the moments when Demeter was describing herself as "Doso", and also connecting with last unit's reading where we read about Mercurius portraying as Sosia makes me think that these mythological gods like to impersonate as others. Is this because they see this as an opportunity to conjugate different personality traits and try new identity or roles? Or perhaps it's to test those around her for character and to educate the differences between good and the bad for back then.
