Aman Doger is the best-known named monster of the Nubian Nile, a water ogre whose name joins aman, 'water,' to doger. In folklore it is imagined with midnight-dark skin, fiery upright eyes, long tails, donkey-like legs and great ears, and an insatiable appetite for palm dates and for little children who stray to the river. It is above all a nursery bogey, summoned to keep children away from the dangerous bank, and it belongs to the wider class of malevolent water beings, the dogri. John Kennedy gave the creature a dedicated study in the Journal of American Folklore in 1970, treating it as a genuine and discrete figure of the Nubian imagination rather than a mere generic ogre. Sources vary in the details of its shape, but its role as devourer and river-terror is constant.
