The illustrations are wonderful. But every culture in the world, from Incas to Arabs to Englishmen, get at least one illustration and one explanation. There's an illustration of a church, a minaret and a Moslem school. Jews were a strong presence in the Middle Ages throughout the world, so the omission is glaring. I suppose the striking difference would be the extent to which Jews approached a near-100-percent literacy, even then. But given that the merchant who might have sold the cloth to that woman with the cone-shaped hat might have been Jewish, perhaps it would have been truly illustrative of Medieval life, since Jews were required to wear distinctive clothing wherever they went.
The effect is to show a book with deficiencies.
