Penrose stairs

 * . Penrose stairs refers not to a specific work of art, but to a type of endless staircase figure in any artwork. Penrose stairs appear in ' by M. C. Escher, in the movie ', as a symbol in political cartoons, in sculpture, &c. ~ Röbin Liönheart (talk) 20:58, 17 February 2013 (UTC)


 * Agree: I would keep Penrose stairs, Penrose triangle, etc. as they are types of optical illusion, and countable: not like Mona Lisa, one specific object. Equinox ◑ 21:41, 17 February 2013 (UTC)


 * I thought that Penrose stairs was a term for any staircase looped in that impossible way, not just the specific drawing Penrose made. The citations I've put at Citations:Penrose stairs are a start towards demonstrating that, so I'd keep that entry. - -sche 22:18, 17 February 2013 (UTC)
 * Accordingly, I would change the definition from "A drawing by Penrose..." to "A set of stairs, originally depicted in a drawing by Lionel Penrose and Roger Penrose, that are impossible to fully construct as a three-dimensional object." At least, I would add "...or a set of stairs like the one depicted in that drawing" to the end of the current definition. - -sche (discuss) 22:38, 19 February 2013 (UTC)


 * Angr voted to "keep as translation targets all that have foreign names distinct from the English names (not counting mere transliterations into other writing systems). That appears to be all of these except Guerrillero Heroico." (see his comment in the Mona Lisa section) note placed by - -sche (discuss) 19:50, 19 February 2013 (UTC)
 * Keep as a descriptor for a class of things, rather than an individual work. bd2412 T 14:26, 20 February 2013 (UTC)


 * Would anyone like to provide some citations to prove it's a class of object? Siuenti (talk) 19:22, 21 February 2013 (UTC)
 * 2012, Eddie J. Smith, Halloween, Hallowed Is Thy Name, page 255:
 * It is like the image below, called the Penrose Stairs. We can climb and descend the stairs of human intelligence and never get anywhere. All the while we are merely going around in a circle, as if caught in the trap of the Penrose stairs.
 * Note that the image actually provided is a rather shoddy generic drawing of an unending stair set, and not an exact reproduction of Penrose's original artwork. bd2412 T 23:47, 21 February 2013 (UTC)
 * Keep. No reason for deletion relating to WT:CFI was stated. An entry for a common noun. --Dan Polansky (talk) 18:15, 22 February 2013 (UTC)
