Taken literally (rather than as indicating an acquaintance with Posidonius through his works: Vivian Nutton, Ancient Medicine, p. 203), this would place Athaenaeus in the 1st century BC instead of the 1st century AD. Galen's dating is defended by Kudlien, Hermes 90 (1962), pp. 419ff, RE Suppl. XI pp. 1097ff, cited by I.G. Kidd Posidonius vol. 3, p. 45 (T51).
