The aged monk Maël is blown off course to an Arctic island and, half-blind and deafened, mistakes a colony of great auks for human pagans and baptises them all. Heaven then holds a solemn theological council over whether sacrament by error is binding. It resolves the problem by turning the birds into humans so they can bear souls, and the Penguin nation's sacred origin rests on this clerical blunder.
When a strong Penguin clubs his neighbour to seize a field, the missionary first condemns it as murder. The satire claims that ownership and the state originate in successful force, which is retroactively sanctified as right and inherited as nobility.
In the Pyrot affair, a parody of the Dreyfus Affair, a Jewish officer is accused of stealing eighty thousand trusses of hay. When no real evidence exists, the war minister manufactures ever more documents. The piles of forgeries become too vast to examine and so seem irrefutable. Guilt is established by patriotic loyalty to the army, and doubting the evidence is itself treated as treason.
The Penguins' plutocratic megacity, built on extreme inequality, is blown apart by anarchist bombs. The ruins become shepherds and villages again, and cities, commerce and wealth slowly rebuild toward the same collapse. History is presented not as progress but as a repeating loop in which the forces that build a civilisation also prepare its destruction.
