Isis was the Ancient Egyptian Goddess of motherhood, magic and fertility, patron of women, sinners and the down-trodden.  According to the account of the Greek historian Plutarch, when Isis died a statue was placed over her grave, and a dark veil draped over that statue.  An inscription below the statue read

I am all that has been, that is, that shall be, and none among mortals has yet dared to raise my veil. (source)
