“Having resided at Agra till there was no more to be learned, I travelled into Persia, where I saw many remains of ancient magnificence, and observed many new accommodations of life. The Persians are a nation eminently social, and their assemblies afforded me daily opportunities of remarking characters and manners, and of tracing human nature through all its variations.

“From Persia I passed into Arabia, where I saw a nation at once pastoral and warlike; who live without any settled habitation; whose only wealth is their flocks and herds; and who have yet carried on through all ages an hereditary war with all mankind, though they neither covet nor envy their possessions.”
