We observe that, actually, the number of functions is quite limited. Only some 31 functions may be noted. The action of all tales included in our material develops within the limits of these functions. The same may also be said for the action of a great many other tales of the most dissimilar peoples. Further, if we read through all of the functions, one after another, we observe that one function develops out of another with logical and artistic necessity. We see that not a single function excludes another. They all belong to a single axis and not, as has already been mentioned, to a number of axes.
