The unit of length reported by the greek historian Homer circa 800 b.c. used by the heros of the Illiad and the Odyssey circa 1100 b.c. was the cubit, the author Pelasgian and that unit proven by the cubit dimensions of some of the tombs of the ancient Etruscans of iron age Italy, those of pelasgian stock as confirmed by Virgil in his book The Aeneid.
In the Iliad and Odyssey, what later would be known as Athens was called Cecropia, named after Cecrops up from Egypt circa 1400 b.c., who first made the Acropolis a large citadel. At that time before the invasion of Troy, king Cecrops probably brought from north Africa and Crete the worship of Neith (Libya) or Athena Potnia (Crete), and then centuries later, probably circa 800 b.c., the worship of Athena had become so great Cecropia was renamed Athens.
By the time of the first Olympics at 776 b.c., the unit of measure was the olympic foot, not the cubit, for the foot racing event distances, the foot which had become dominant probably not just coincidentally when the worship of Athena usurped the Pelasgian tradition and culture of measure by the cubit, both units however earth commensurate, known then seeing http://genesisveracityfoundation.com/earth-measure-geometry/
