I am interested in what is the correspondence between the Four Mothers (Sarah, Rivkah, Rachel and Leah) and the Four Exiles (Babylonian, Persian/Medean, Greek and Roman).
There is a lot of indirect evidence that such a relationship exists. Particularly, by the Seder, I've often heard quoted in the name of the Maharal that the 4 cups represent the 4 mothers, in order of being drunk (i.e. Kiddush, Maggid, Birchas HaMazon, Hallel correspond to the above list of Mothers in the same order), and the same 4 cups represent the 4 exiles, but I never saw what is the relationship between these.
Could someone please explain it to me. Thank you very much.
