`  Some further remarks: *If I may add something from my sources. A renowned Greek encyclopedia, Helios (ed. 1953) (Volume: Greece, pages: 1147-1160), presents as major gods the following: Zeus, Hera, Athena, Apollo, Artemis, Hephaestus, Aphrodite, Ares, Hermes, Demeter, Dionysus, Poseidon and Hestia. It gives 13 major gods, and does not include Hades. *I recall from my editing of Greek mythology (during its successful FARC) what I had written stating H.W. Stoll, Religion and Mythology of the Greeks, 8: ``The limitation of their number [of the Olympians] to twelve seems to have been a comparatively modern idea.`` *From a search in ``Google Book`` I get conflicted information. For instance, Encyclopedia Americana says that Hades was not one of the ``12`` and that Dionysus often displaces Hera. In Gardner's Art Through the Ages, p. 107, I see a list identical to the one Sthenel gives, but it is also mentioned that ``Hades was of equal status``. In Lesley Adkins-Roy A. Adkins, Handbook to Life in Ancient Greece, 183, I read: ``According to Hesiod there were 12 Olympians: Zeus, Poseidon, Hera, Athena, Apollo, Artemis, Aphrodite, Hermes, Demeter, Dionysus, Hephaestus and Ares.`` So, here Dionysus and Demeter are included but not Hades and Hestia! In my version of Britannica (2001-CD ROM), I did not find something helpful; maybe somebody else can research there better! I still have to check the most renowned modern Greek encyclopedia Papyrus-Larousse-Britannica, but I think that the most comprehensive approach is the one I read in Religious Facts: :``There were fourteen different gods recognized at some point as Olympians, though never more than twelve at one time. Zeus, Hera, Poseidon, Ares, Hermes, Hephaestus, Aphrodite, Athena, Apollo, and Artemis were always considered Olympians. Hestia, Demeter, Dionysus, and Hades are variable gods among the Twelve.`` I think that this is quite accurate: there was a clear group of 10 major gods, and some others included or not according to different sources, and this is the spirit I think this article should reflect. Now, if there is a consensus towards this direction, we can find out the exact wording (maybe something similar to ``Religious Facts`` or any other helpful proposal), include the necessary sources and references, and close this issue.  `
