Herakles in Hermitage, St.Petersburg (Hellenistic times).
No doubt, it is this very comic and childish Herakles who could participate in Alcestis' (doubtful) resurrection. This funny and playful Herakles took the dead wife of Admetus out of her grave and brought her (or it; whom - that is the question) back to mourning Admetus. For more details about the joke the hero played, himself in highly good mood, on the poor king see Euripides' Alcestis.
