Pliny, Natural History II, trans. H. Rackham (Loeb, 1947), 560-1 (Book VII c.20.83), names Athanatus as an example of immense strength rather than exeptional height, since he was able to walk across a stage wearing a lead breastplate weighing 500 pounds and boots weighing a further 500 pounds. He is also mentioned by Chassaneon, 34.
