The earliest dated decree-class document in the matrix-hub corpus (c. 500 BCE). A bronze tablet from Olympia recording a 100-year alliance between the Eleans and the Heraeans, in Elean Doric dialect with retained digamma (ϝ). The opening formula ἁ ϝράτρα — "this is the covenant" — establishes a stable inter-state-treaty genre five centuries before its Hellenistic and Roman descendants.本文献集中年代最早的法令类文献（约公元前500年）。它是一块出自奥林匹亚的青铜板，记录埃利斯人与赫拉伊亚人之间为期一百年的同盟，以埃利斯多里斯方言写成，并保留双伽马（ϝ）。开篇公式 ἁ ϝράτρα（“此为盟约/约言”）在希腊化与罗马后继文书出现前五个世纪，已经显示出稳定的城邦间条约体例。
