Some elements run like a red thread through these works : a little girl viewed from behind is standing in front of a tree and writing on its trunk or walking along a forest path surrounded by tiny rows of trees. Taking a closer look, one can see that in some depictions of the tree and in other depictions the girl, sometimes even both, dissolve into Persian calligraphy. It is a poem composed by the artist, but written backwards it cannot be read.

The title of the series insinuates to Horace’s in art history well known statement "Ut pictura poesis". He meant that poetry resembles painting and unleashed a long battle between philosophers, artists and poets in relation to the question as to which form of art would provide the most aesthetic pleasure. By exchanging the words "poesis" and "pictura" Katayoun shows that both are interrelated and the two going together hand-in-hand. The relativity of things - everything is only a question of the point of view - is one of Rouhi’s focal aspects.
