Sir John Mandeville [was] an encyclopedist whose mostly invented stories still ring true, thanks to his gift for writing the first realistic Western fiction since Petronius. We do not know who this man was or even what language he wrote in, but modern textual analysis suggests that he rarely left his study. Rather than travel, he scavenged and plagiarized the works of others, improving their prose as he claimed their discoveries. In a period of continental isolation, Mandeville satisfied Europe's appetite for news by making up an East that sounded real. In expanding editions and translations, his became the most popular prose book of the Middle Ages.
