The illustrations are brightly colored and support the stories well. They have a flavor of ancient Indian art or Persian miniatures, and this is carried out to good effect with the page decorations as well, which are rendered in bright colors of red, gold, and bright blue.
The addition of side bar information explaining topics such as Medicine in the Muslim World or the historical impact of wheat are also interesting and help readers to understand the stories. There is a very complete and helpful map at the end of the book, and a helpful index is included.
While Napoli's collections are fun to read for pleasure, they are complete, annotated, and formatted in a way that they are useful to readers who may need to do research as well. The D'Aulaires managed to combine these elements into beautifully crafted collections, but these new titles from Napoli definitely give those a run for their money!
