Tradition loves to embroider a story with names and definite details. The prudent Attic vase-painter gives us only a nameless ‘Giant.’ Others knew more. Pausanias[33] had heard the builders’ actual names and tried to fix their race. He tells us—just as he leaves the Acropolis—‘Save for the portion built by Kimon, son of Miltiades, the whole circuit of the Acropolis fortification was, they say, built by the Pelasgians, who once dwelt below the Acropolis. It is said that Agrolas and Hyperbios ... and on asking who they were, I could only learn that in origin they were Sikelians and that they migrated to Acarnania.’ Spite of the lacuna, it is clear that Agrolas and Hyperbios are the reputed builders. The reference to Sicily dates probably from a time when the Kyklopes had taken up their abode in the island. The two builder-brothers remind us of Amphion and Zethus, and of their prototypes the Dioscuri[34]. Pliny[35] tells of a similar pair, though he gives to one of them another name. ‘The brothers Euryalos and Hyperbios were the first to make brick-kilns and houses at Athens; before this they used caves in the ground for houses.’ The names of the two ‘Pelasgian’ brothers are, as we know from the evidence of vase-paintings[36], ‘giant’ names, and _Hyperbios_ is obviously appropriate. The names leave us in the region of myth, but the tradition that the brothers were ‘Pelasgian’ deserves closer attention. In describing the old wall we have spoken of it as ‘Pelasgian,’ and in this we follow classical tradition. Quoting from Hecataeus (circ. 500 B.C.), Herodotus[37] speaks of land under Hymettus as given to the Pelasgians ‘in payment for the fortification wall which they had formerly built round the Acropolis.’ Again, Herodotus[38] tells how when Kleomenes King of Sparta reached Athens, he, together with those of the citizens who desired to be free, besieged the despots who were shut up in the Pelasgian fortification. A Pelasgian fortification, a constant tradition that Athens was inhabited by Pelasgians—we seem to be on solid ground. Yet on a closer examination the evidence for connecting the name of the fortification with the name ‘Pelasgian’ crumbles. In the one official[39] inscription that we possess the word is written, not Pelasgikon, but Pelargikon. In like manner, in Thucydides[40], where the word occurs twice, it is written with an _r_. Pelargikon is ‘stork-fort,’ not Pelasgian fort. The confusion probably began with Herodotus, who was specially interested in the Pelasgians. Why the old citadel was called ‘stork-fort’ we cannot say—there are no storks there now—but we have one delightful piece of evidence that, to the Athenian of the sixth century B.C., ‘_stork-fort_’ was a reality.
