This article offers a re-examination of the theoi (‘gods’) heading which appears regularly on inscriptions in the ancient Greek world. Long noted, the heading has also long been passed over, often considered so formulaic as to lack much significance. This paper explores the consequences of taking theoi seriously as a reference to the divine, by investigating the function and meaning of the heading in the classical period. It makes use of two case studies, the financial building inscriptions from the Athenian (...) Akropolis and the epigraphic corpus from Oropos, to set out the most important characteristics of the formula. By placing the theoi heading in a broader context of other types of divine formula found on inscriptions, and by paying particular attention to the crucial aspect of the heading’s non-specificity, this article contends that the theoi or theos formula should not be understood as a prayer or appeal to the gods. Instead, it is a statement of presence of the divine and a recognition of divine power. (shrink)
