2 3 Arithmetica

In Plato's Timeus the Demiurg's means of creation are musical and geometric proportions:

" And he proceeded to divide after this manner:
-First of all, he took away one part of the whole [1],
and then he separated a second part which was double the first [2],
and then he took away a third part which was half as much again as the second and three times as much as the first [3],
and then he took a fourth part which was twice as much as the second [4],
and a fifth part which was three times the third [9],
and a sixth part which was eight times the first [8],
and a seventh part which was twenty-seven times the first [27]."
