Bertrandon de la Broquière,the Spy of Philip the Good, Duke of Burgundy, underwent a pilgrimage in the Holy Land and Turkey during 1432-1433. He wrote an of about his travels in the genre of an adventurous memoir entitled Le Voyage d’outre-mer (The Overseas Voyage).
Here, the spy's attention was held mainly by Islam and the Turcs, many of whom he's portrayed in conspiciously sympathetic ways. In the fifteenth century, no other travelogue revealed the author's personal quest for a more perceptive understanding of cultural differences.
