The narrative begins with a crew of European sailors lost in the South Sea after months of wandering off course from Peru toward China. Facing starvation and death, they sight the unknown shores of Bensalem, an isolated and highly developed island commonwealth. Although initially warned away by officials bearing a sealed scroll in multiple ancient languages, the sailors are soon treated with remarkable humanity, provided with food, medical care, and comfortable quarters in the Strangers' House.
As the crew recovers, they gradually learn about the laws, customs, and history of this hidden civilization from local dignitaries and merchants. Bensalem is governed by wise laws established by its ancient king Solamona, who instituted a policy of strict isolation combined with carefully regulated overseas intelligence gathering. The island remains entirely unknown to the rest of the world because its inhabitants forbid outward travel and strictly control the entry of strangers, ensuring peace, high moral standards, and the preservation of traditional virtues.
The spiritual foundation of Bensalem is revealed to be rooted in a miraculous biblical event. Decades after the ascension of Jesus, the city of Renfusa witnessed a pillar of light topped by a luminous cross rising from the sea. When local scholars approached in boats, the light dispersed, leaving behind a cedar chest containing the canonical scriptures and a letter from the Apostle Bartholomew declaring salvation for the land. This miraculous event preserved the population from infidelity and shaped their deeply reverent Christian culture.
Central to the prosperity and intellectual life of Bensalem is Solomon's House, an immense scientific institution that serves as the heart of the kingdom. During a private audience with one of the Fathers of the institution, a sailor receives a detailed account of its vast resources and organizational structure. Solomon's House features deep underground caves, high towers for meteorological observation, large lakes, and specialized laboratories designed to study natural phenomena, cure diseases, and develop new inventions for the improvement of human life.
The society also places immense value on family life and public morality, exemplified by traditional celebrations like the Feast of the Family, which honors parents with numerous living descendants. The inhabitants display exceptional chastity, community cohesion, and reverence for natural order, contrasting sharply with the moral decay they perceive in European nations. The text concludes with the Father of Solomon's House granting the narrator permission to publish this account for the benefit of other nations before the manuscript breaks off.
