Ἑρκεῖος Ζεύς

[Meaning Zeus] for whom altars are set up in the courtyard inside a fence [herkos]; for they used to call the enclosure-wall a e(/rkos. Those who had a Zeus Herkeios had a share in the constitution.¹
A e(rki/on [was] the enclosure-wall of the courtyard, or the roof of the house; for the house [is called] e(rki/on. Sophocles [writes]: "before, bound to the pillar of the house-roof, [...] first having his back bloodied with a lash, he dies."²
Also [sc. attested is] e(/rkios, [meaning] a protector, a guard.³
