Capt. Richard Francis Burton was a lunatic, in the finest British tradition.

"Entering the holy city of Mecca disguised as a Muslim, Burton undertook this journey amid considerable risk to his life as a Westerner. His pilgrimage, part of the hajj required of Muslims, involved not only a physical journey but a deep commitment to understanding the cultural and religious practices of the region. He meticulously prepared for this venture, studying the Arabic language and customs, and even undergoing circumcision to authentically embody a devout Muslim.

During his six days in Mecca, Burton visited numerous sacred sites, including the Kaaba and Mount Arafat, while documenting his experiences and observations. His accounts later culminated in a three-volume work that gained widespread acclaim in England, making him a notable figure in the field of travel literature. "
