3D modelling of the Ennedi rock art. The dual way of representing humans related to gender, typical of the Hohou style (Middle Cattle Period), is expressed by women in skirts and men with visible body fat. The waist to hip ratio of the mannequin is equal to 0.98. In the real world, this ratio is possible but would translate into severe obesity. Such physical condition is made even more apparent by the tapering head, sometimes recalling an animal head as in the case of the paintings shown in the backdrop (from the Sivré I shelter). In the model, the tapering of the head and feet require a propagating scale reduction respectively equal to -25% and -24%. The standardised pose realistically simulated in 3D by the mannequin indicates a preference for a lateral point of view in human depictions. Reference: Alessandro Menardi Noguera 2018.
