Thomas Bulfinch 
Bulfinch’s Mythology: Fable, Chivalry, Charlemagne 

The introduction begins: ’The literature of our time, as of all the centuries of Christendom, is full of allusions to the gods and goddesses of the Greeks and Romans. Occasionally, and, in modern days, more often, it contains allusions to the worship and the superstitions of the northern nations of Europe. The object of this book is to teach readers who are not yet familiar with the writers of Greece and Rome, or the ballads or legends of the Scandinavians, enough of the stories which form what is called their mythology, to make those allusions intelligible which one meets every day, even in the authors of our own time.’
