Yeah, that's right, this guy. Mr. Circumnavigation.
Friend of mine's daughter has a class project due (Friday) so I figured I'd appeal to the hive-mind for the kind of winning, teacher-impressing anecdotes she won't find from Encarta or the World Book Encyclopedia.
The Web being what it is, some Ph.D. candidate midway through her thesis on Juan Sebastian Elcano will stumble across this and post the perfect final tidbit here in comments. At least, that's what I'm hoping for.
Thanks in advance for any help.
UPDATE: Thanks again for playing along at home. (SV, you were right about the grade-school appeal of the gross-out details from Pigafetta's journal, thank you.)
