Reading fine book, Sienese Painting, by Timothy Hyman (a painter himself). The miniature narrative images - saints' lives, journey of Dante, Virgil & Beatrice - resemble graphic novels of today. In one scene, reading from left to right, you'll see a figure in three different actions (falling sick, visited by angel, cured...), like a cartoon.
Siena loved the Divina Commedia (maybe partly because Dante was so hard on his home town Florence). Public readings were given outdoors on feast days.
