The Phaeacian episode of Homer's Odyssey (Books 6–8, 13) presents a society of unusual technological and cultural sophistication: bronze walls flashing in the sun, perennial orchards fed by twin fountains with hidden irrigation channels, and ships requiring neither rudder nor pilot. Scholars have noted structural parallels between these features and Plato's Atlantis narrative (Timaeus and Critias, c. 360 BCE), but the comparison has remained largely in the domain of literary observation rather than systematic geo-mythological analysis. This paper proposes a unified framework: that both the Phaeacian episode and the Platonic Atlantis tradition preserve, through different cultural and literary mediations, distorted memories of the Afar Depression's landscape during the African Humid Period (AHP, c. 15,000–5,000 BP), when the region supported freshwater mega-lakes, perennial drainage systems, abundant vegetation, and a concentric paleolake shoreline structure now preserved in the geological record. The argument proceeds through three stages: close reading of the Phaeacian episode against the Atlantis narrative to establish the structural parallels as specific rather than generic; comparison of both traditions against documented Afar AHP geology and paleoecology; and assessment of the transmission mechanisms through which Afar landscape memory could have reached the Homeric and Platonic literary traditions via Egyptian Punt expeditions, Red Sea trade networks, and Mycenaean–Egyptian cultural exchange. The hypothesis is presented with explicit acknowledgement of its speculative character: no direct textual or archaeological link between the Afar and Homeric or Platonic traditions exists, and the transmission chain is inferred rather than documented. The paper's contribution is to demonstrate that the Phaeacia–Atlantis structural parallel is most coherently explained as a shared geographical substrate rather than as direct Platonic–Homeric literary dependency, and that the Afar AHP landscape satisfies the criteria of that substrate with greater specificity than previously proposed candidates.
