Except for the variegated texts collected under the rubric of Testamentum Salomonis, there are precious few mentions of the famed 'Seal of Solomon' in Greek literary sources. In Greek epigraphic documents, however, we find numerous attestations for a performative apotropaic use of the seal. My paper will therefore explore different types of Greek epigraphic sources (curse tablets, amulets, gems, magical papyri) containing mentions of the Seal of Solomon, compare the pragmatics of its use and relate these instances to the extant literary texts.
