This process seems to have involved some form of divination or cleromancy. This was 'to know precisely the will of Heaven concerning their matrimonial union' ("vide" cleromancy). Hermes is associated with divination by lottery, otherwise known as cleromancy. Apollo transfers to Hermes a skill in cleromancy, upon the request of Hermes. They are connected with divination in general, and cleromancy in particular. The "I Ching" uses a type of divination called cleromancy, which produces apparently random numbers. Cleromancy was practiced at places including Dodona, and by "the Pythia" at Delphi.
