The Pythagoreans called the number ten: “Cosmos”, “Ouranos” and, among the Muses, Ourania, “Pan”, “Heimarmene and Aion/Aeternitas”, “Kratos (Strength/Power) and Pistis (Faith) and Ananke (Necessity)”, “Atlas” and, in a word, “God”, “Phanes” and “Helios” - and “Panteleia” (accomplishment/fulfillment of all things). (cf. Iambl, Theol. Arithm. 80-86)
“The cosmos is, as we have seen, the only one of its kind and unique (i.e. a Monad); next we discover that it is necessary that there is the tangible and visible in it (i.e. a Dyad); next that since there is considerable separation between these things, some third thing is needed (in order to bring them together); next we find out that the middle term involves two forms, and thus we arrive at the Tetrad. This was therefore what the Pythagorean hymn to number said as well: ‘that it proceeds from the inviolate abyss of the Monad, until it should arrive at the sacred Tetrad’ and this gives birth to the Decad which is 'the Mother of all things’. The father of the Golden Verses also glorifies the Tetrad calling it 'the fountain of ever-flowing Nature’. For the cosmos was ordered (kosmein) by the Tetrad, which proceeded from the Monad and the Triad, and it is completed at the Decad in as much as this is inclusive of all things… the decad is the number of the world…the Pythagoreans consider the decad as adapted to the Demiurgus, and to Fate.”
