I've noted the books that were recommended by Connecting with History. The majority are ones I found in other ways.
The Marvellous Blue Mouse by Christopher Manson is the tale of a foolish mayor during the time of Charlemagne. His ignorance and greed are put on display for all to see by a marvellous mouse. My children loved this book, laughing out loud at the foolish mayor and practically cheering the good friend of Charlemagne who saves the city.
A Saint and His Lion: The Story of Tekla of Ethiopia by Elaine Murray Stone, illustrated by Cecile Sharratt, is the wonderful tale of St. Tekla of the Ethiopian Orthodox Church. He demonstrates great compassion, perseverance, and love in following God's call and his ministry.
The Kitchen Knight: A Tale of King Arthur by Margaret Hodges, illustrated by Trina Schart Hyman, retells one of the Arthurian legends, the tale of Sir Gareth. If you like Saint George and the Dragon, you'll enjoy this book as well.
The Empty Pot by Demi tells the story of a lone trustworthy child in China who refuses to cheat in an attempt to woo the favor of the Emperor. It is one of my favorite picture books, also available at RC History.
