He is also invoked in the Gurôb Papyrus of the mid-3rd century BC.<ref> Graf and Johnston, ''Ritual Texts'', p. 189.</ref>
Because Eubuleus seems to be a human being in the narrative alluded to by the scholiast to Lucian, he has sometimes been considered a [[Greek hero cult|hero who received cult veneration]], as are Triptolemus and even Iacchos.<ref>William Henry Denham Rouse, ''Greek Votive Offerings: An Essay in the History of Greek Religion'' (Cambridge University Press, 1902), p. 28.</ref>
