This essay was written in 1908-1910 while I was studying at Oxford as
Fellow of the Society of American Women in London. Material on the
subject of travel in any century is apparently inexhaustible, and one
could write many books on the subject without duplicating sources. The
following aims no further than to describe one phase of Renaissance
travel in clear and sharp outline, with sufficient illustration to
embellish but not to clog the main ideas.
