The story told in this book is based upon legendary history, and the statements on which it is founded appear in the chronicles of Abou-djafar Mohammed Tabari. This historian was the first Mussulman to write a general history of the world. He was born in the year 244 of the Hejira (838-839 A.D.), and passed a great part of his life in Bagdad, where he studied and taught theology and jurisprudence. His chronicles embrace the history of the world, according to his lights, from the creation to the year 302 of the Hejira.

In these chronicles Tabari relates some of the startling experiences of El Khoudr, or El Kroudhr, then Vizier of that great monarch, the Two-Horned Alexander, and these experiences furnish the motive for those subsequent adventures which are now related in this book.

Some writers have confounded the Two-Horned Alexander with Alexander the Great, but this is an inexcusable error. References in ancient histories to the Two-Horned Alexander describe him as a great and powerful potentate, and place him in the time of Abraham. Mr. S. Baring-Gould, in his "Legends of the Patriarchs and Prophets," states that, after a careful examination, he has come to the conclusion that some of the most generally known legends which have come down to us through the ages are based on incidents which occurred in the reign of this monarch.

The hero of this story now deems it safe to speak out plainly without fear of evil consequences to himself, and his confidence in our high civilization is a compliment to the age.
