Legends of Charlemagne

According to Wikipedia: "Bulfinch's Mythology is a classic work of popularized mythology, still in print 150 years after the first work, Age of Fable, was published in 1855. The compilation, assembled posthumously by Edward Everett Hale, includes various stories belonging to the mythological traditions known as the Matter of Rome, the Matter of Britain and the Matter of France, respectively. Bulfinch wrote in his preface:  "Our work is not for the learned, nor for the theologian, nor for the philosopher, but for the reader of English literature, of either sex, who wishes to comprehend the allusions so frequently made by public speakers, lecturers, essayists, and poets, and those which occur in polite conversation."
