Foreshorten

If an object or person is foreshortened it is depicted as though receding from the viewer into the picture space.

To achieve this effect successfully requires knowledge of the laws of perspective. Notable examples of this illusion in the National Gallery include the fallen knight in Uccello's 'Battle of San Romano', and the arm of the disciple on the right in Caravaggio's 'Supper at Emmaus'.
