 He appears in the earliest ballads, and is mentioned in even earlier sources, such as Andrew of Wyntoun's "Orygynale Chronicle" of around 1420 and Walter Bower's expansion of the "Scotichronicon", completed around 1440.Later ballads name additional Merry Men, some of whom appear in only one or two ballads, while others, like the minstrel Alan-a-Dale and the jovial Friar Tuck, became fully attached to the legend.Several of the Robin Hood ballads tell the story of how individual Merry Men join the group; this is frequently accomplished by defeating Robin in a duel.
