 Oliver, following R. Berndt (1952), argues that the Djanggawul cycle is a dramatic enactment of Arnhem Land's monsoon cycle, which shaped Aboriginal food procurement activities.Oliver says, "This is not to say that a dramatic presentation was needed to familiarize the Arnhemlanders with the stark reality of their monsoon climate, and of its direct effects upon their lives; about that they were deeply aware.What the rituals did was to rationalize that climate in mythical terms (a reassuring thing in itself) and to provide them with a doubtless satisfying means of attempting to insure the regular recurrence of the rains.
