H. Rider Haggard 
Ivory Child 

The timeless adventure featuring explorer Allan Quatermain, the inspiration for Indiana Jones, from one of the first authors of the “Lost World” genre.  The Ivory Child is a novel by H. Rider Haggard featuring Allan Quatermain—explorer, treasure hunter, and adventurer. In one of his strangest undertakings yet, Quatermain finds himself in the throes of a war between two African tribes, one of them led by an evil spirit that resides in the body of a gigantic elephant.   Two foreigners, Harût and Marût, call upon Quatermain by the name he uses among the Africans: Macumazana. They are convinced by divination that only Quatermain can defeat the elephant god and save Africa from an epic battle destined to plunge the continent into chaos . . .
