The words "Middle Ages" conjure up pictures of castles and cathedrals, battles and tournaments, knights and dragons, lords and ladies. We get these mental images from the pictures found in illuminated manuscripts—handmade books as beautiful and precious as jewels. The Free Library has the Philadelphia area's largest collection of Medieval and Renaissance illuminated manuscripts. You can find them in the Rare Book Department on the third floor of the Central Library, 1901 Vine Street.
