BTW - my dictionary states that most legends are:
1. a nonhistorical or unverifiable story handed down by tradition from earlier times and popularly accepted as historical.
2. the body of stories of this kind, especially as they relate to a particular people, group, or clan: the winning of the West in American legend.
3. an inscription, especially on a coat of arms, on a monument, under a picture, or the like.
4. a table on a map, chart, or the like, listing and explaining the symbols used. Compare key1 ( def 8 ) .
5. Numismatics , inscription ( def 8 )
