Dragon (Dutch: Draak) is a wood engraving print created by Dutch artist M. C. Escher in April 1952, depicting a folded paper dragon perched on a pile of crystals.

[1] It is part of a sequence of images by Escher depicting objects of ambiguous dimension, including also Three Spheres I, Doric Columns, Drawing Hands and Print Gallery.

[2][3] Escher wrote "this dragon is an obstinate beast, and in spite of his two-dimensions he persists in assuming that he has three".

[1] In Gödel, Escher, Bach, Douglas Hofstadter interprets the dragon's tail-bite as an image of self-reference, and his inability to become truly three-dimensional as a visual metaphor for a lack of transcendence, the inability to "jump out of the system".

[4][5] The same image has also been called out in the scientific literature as a warning about what can happen when one attempts to describe four-dimensional space-time using higher dimensions.
