The passage referred to occurs in Congreve's _Love for Love_, Act II. Sc.
5. Cervantes had before designated Pinto as the "prince of liars." It seems
that poor Pinto did not deserve the ill language applied to him by the
wits. Ample notices of his travels may be seen in the _Retrospective
Review_, vol. viii. pp. 83-105., and Macfarlane's _Romance of Travel_, vol.
ii. pp. 104-192.
