La trahison des images

A <span property="artform">painting</span> also known as <span>The Treason of Images</span> or <span property="alternateName">The Treachery of Images</span>.

<div property="description">

The painting shows a pipe. Below it, Magritte painted, <q lang="fr">Ceci n'est pas une pipe.</q>, French for "This is not a pipe."

His statement is taken to mean that the painting itself is not a pipe. The painting is merely an image of a pipe. Hence, the description, "this is not a pipe."

Similarly, the image shown above is neither a pipe nor even a painting, but rather a digital photograph.

The painting is sometimes given as an example of meta message conveyed by paralanguage. Compare with Korzybski's <q>The word is not the thing</q> and <q>The map is not the territory</q>. </div>

My Bed

My Bed, first created in <time property="dateCreated" datetime="1998">1998</time>, is an <span property="artform">installation</span> by the British artist Tracey Emin.

<div property="description">

<cite>My Bed</cite> was exhibited at the Tate Gallery in <time datetime="1998">1999</time> as one of the shortlisted works for the Turner Prize. It consisted of her bed with bedroom objects in an abject state, and gained much media attention. Although it did not win the prize, its notoriety has persisted. </div>

• Artist: <span property="creator" typeof="Person"> <span property="name">Tracey Emin</span> </span>

The artwork generated considerable media furore, particularly over the fact that the <span property="artMedium">bedsheets</span> were stained with bodily secretions and the floor had items from the artist's room (such as <span property="artMedium">condoms</span>, <span property="artMedium">a pair of knickers</span> with menstrual period stains, other detritus, and functional, everyday objects, including a <span property="artMedium">pair of slippers</span>). The <span property="artMedium">bed</span> was presented in the state that Emin claimed it had been when she said she had not got up from it for several days due to suicidal depression brought on by relationship difficulties.

<div property="description">

<cite>Still Life under the Lamp</cite>, from 1962, made when the artist was eighty years old, are counted among Picasso’s most important works in linocut, a technique that he explored in the late 1950s and early 1960s. The progressive proofs show the step by step sequence by which Picasso created his linocut images showing the development of the image into its final form.
