THE ANDROPHAGOI were a tribe of African cannibals who fed exclusively on the flesh of other men.

Their neighbours included the Agriophagoi who ate the flesh of lions and panthers and the Pamphagoi who devoured everything.

Philostratus, Life of Apollonius of Tyana 6. 23 - 25 (trans. Conybeare) (Greek biography C1st to C2nd A.D.) :
“The Nasamones and the Androphagoi (Man-Eaters) and the Pygmaioi (Pygmies) and Skiapodes (Shadow-Foots) people are also tribes of Aithiopia, and they extend as far as the Okeanos Aithiopos (Ethiopian Ocean), which no mariners ever enter except as castaways who do so against their will.”

Pliny the Elder, Natural History 6. 195 (trans. Rackham) (Roman encyclopedia C1st A.D.) :
"Then come regions [in Africa] that are purely imaginary : towards the west [of the Aethiopian kingdom of Meroe] are . . . the Agriophagi (Wild-beast-eaters), who live chiefly on the flesh of panthers and lions; the Pamphagi (Eat-alls), who devour everything; the Anthropophagi (Man-eaters), whose diet is human flesh."
