Idyll in the modern Russian poetry: to the problem of the genre inner measure

Two poles can be marked in the modern genre model realization: the first will include the works that keep the connection with the invariant, the second deals with those that are only “enrolled” into the idyllic department. So, what lets the idyll, and no other genre, omitting all genre constituting signs, become the author’s integral variation? Maybe, quasi-idylls give rebirth to the dream about the world’s construction, at least, in personal life (the demiurge start), according to the personal laws, as it had been in the herdsman’s singing, – in pastoral.
