In folklore, giants (from Ancient Greek: gigas, cognate giga-) are beings of humanoid appearance, but are at times prodigious in size and strength or bear an otherwise notable appearance. The word giant is first attested in 1297 from Robert of Gloucester's chronicle. It is derived from the Gigantes (Ancient Greek: Γίγαντες) of Greek mythology. Fairy tales such as Jack the Giant Killer have formed the modern perception of giants as dimwitted and violent ogres, sometimes said to eat humans or livestock. In more recent portrayals, like those of Jonathan Swift and Roald Dahl, some giants are both intelligent and friendly.
