Sir Guy of Gisbourne (also spelled Gisburne, Gisborne, Gysborne, or Gisborn) is a character from the Robin Hood legends of English folklore. He first appears in "Robin Hood and Guy of Gisborne" (Child Ballad 118), where he is a hired killer who attempts to kill Robin Hood but is killed by him. In later depictions, he has become a romantic rival to Robin Hood for Maid Marian's love.
The Child ballad "Robin Hood and Guy of Gisborne" dates from 1650 but is much older than that, judging from the similarities with the 1475 play, a fragment of which is preserved in the library of Trinity College, Cambridge.
Robin Hood and Little John walk through the forest. Robin speaks of a bad dream he had, of two men attacking him. While talking, they spot a distant stranger leaning on a tree. Little John tells Robin to wait while he approaches the stranger, but Robin objects as if accused of cowardice, telling John he'd like to break his head. John marches off in a huff, and is promptly captured by the Sheriff of Nottingham and tied to a tree, to be hanged. Meanwhile, Robin goes up to the stranger, Guy of Gisborne, who is clad in a horsehide robe.
Guy's outfit is described thus:
Guy is a hired killer seeking Robin Hood. They have a shooting contest, and Robin wins with ease. Robin identifies himself (as "Robin Hood of Barnsdale", in South Yorkshire) to the suspicious Guy, and the two fight. When Robin trips, Guy stabs him, but (after a brief prayer to Mary) Robin kills him with his sword. He dons the distinctive horsehide, cuts off Guy's head, sticks it on the tip of his bow and slashes the face, rendering it unrecognisable. He then blows Guy's horn to signal victory to the Sheriff. Disguised as Guy, and carrying what he passes off as Robin Hood's head, Robin goes to rescue Little John. He convinces the sheriff to be allowed to kill Little John, but instead cuts him loose with an "Irish knife". John then takes a bow and shoots the Sheriff through the heart.
Although he has made many appearances in 19th and 20th century variants of the Robin Hood legends, Guy's only constant is villainy, but a frequently occurring theme is the "love triangle story" involving Robin, Marian, and Guy, a theme adopted from 19th-century theatrical adaptations.
In Howard Pyle's influential novel the Merry Adventures of Robin Hood (published in 1883), he is shown as a crude, coarse outlaw, known for his cruelty and murderous habits.
