It takes great care to list generations of
biblical figures supposedly all the way from Adam, and even if you account for individuals living for hundreds of years and God's «day» being like a 1000 years, you're still only up to about 13,000 years, at most.
For the depiction of Salome, for example she chooses a version of the
figure which is unusual in that it shows two heads —
supposedly the death mask of Herod alongside the severed head of John the Baptist — which further complexifies the myth of the
biblical figure so richly augmented by the romantic imagination.
