I Was Born Under The Sign Of Aries,

so I was naturally interested,

 when I saw this calligram, the art of making images through the use of words, in this article they illustrate Cicero’s Aratea, a work of astronomy, each animal represents a constellation and the written words in them are taken from an explanatory text by Hyginus (in his Astronomica), 

His words are crucial for these images because the drawings would not exist without them, it is not often in medieval books that image and text have such a symbiotic relationship, each depending on the other for its very existence, the manuscript was from the early Middle Ages (France, 9th century), and is now in the British Museum.
