Riallaro

Published in 1901, Riallaro is the first of two speculative novels written under the pseudonym Godfrey Sweven by New Zealand scholar John Macmillan Brown. The book imagines a hidden archipelago in the South Pacific where exiled groups are forced to develop in isolation, each community shaped by its ruling passion or defect. Into this fragmented world falls a traveler with artificial wings, whose encounters across the islands form a satirical survey of human society.

The narrative blends elements of utopia and dystopia. Each island exposes the dangers of allowing one idea, vice, or ideology to dominate unchecked. Some communities fall into grotesque excess, others into harsh repression, and all reveal the consequences of exclusion from the central utopian homeland. The result is both imaginative adventure and philosophical critique, a reflection on the costs of progress and the frailty of human design.

Riallaro anticipates many themes of twentieth-century dystopian fiction, foreshadowing the cautionary visions of Huxley and Orwell. At the same time, it stands firmly in the British satirical tradition, echoing the voyages of Swift in its use of fantastical lands as moral allegory. As an early science fantasy, it combines speculative devices with social commentary, offering a vivid window into the anxieties and ambitions of its era.
