Here's a couple of interesting Gemini images from Gemini artists. The one on the right is by M. C. Escher. The one below comes from "The Arte of English Poesie" of 1589, an influential compendium of rhetorical and poetic techniques. The column on the left is to be read from bottom up, the 
one on the right from top down. "The Arte of English Poesie" is attributed to George Puttenham about whom little is known (no birthdate, alas) except that he had a brother. This particular, and peculiar, excerpt appears in a selection of work by the Gemini artist Raymond Pettibon (published by Phaidon), in the "Artist's Choice" section.
