It is doubtless that Mandeville`s Travels was a pastiche of miscellaneous facts and traditions extracted from ancient and medieval sources. Nowadays this work tends to be regarded as a `summa`, encyclopedia of travelogues, or a `romance of travels`. Nonetheless its historical significance rests on not only its unprecedented popularity due to an absorbing narrative but also its great influence on the world view of common people as well as many voyagers in the age of Exploration. But, beyond just satisfying readers` curiosity, it intended to give a meaningful lesson through those entertaining stories, especially by satirizing and criticizing the corruption of Christendom. The satire and criticism of the degenerate Christendom implied self-objectification based on cultural relativism. In fact the author did not disparage nor blame so many different customs of heathens but keep his eyes on something in common between `us` and `them` beneath superficial differences. This article inspects such perspectives of the author exposed in two parts of Travels that covered far and strange `that side`(or `beyon half`) such as India, Cathay, and Prester John`s kingdom in the East as well as near and familiar `this side`(or `this half`) including Greece and the Holy Land. It focuses on author`s attitude toward the Orthodox Church and Islam, heathen idolatries and cannibalism, natural religion of `bon sauvages`, and also emphasizes that his argument of a spherical earth was closely related to his enlightened view of the Others.
