In Greek mythology, Agelasta (, , "smile-less stone") was the name of the stone on which Demeter rested during her search for Persephone.
In modern culture, Agelasta inspired the title of a documentary by Philippos Koutsaftis (æïûùÃÂÃÂÿàÃÂÿàÃÂÃÂñÃÂÃÂîÃÂ), called Agelastos Petra (ÃÂóÃÂûñÃÂÃÂÿààÃÂÃÂÃÂñ, "smile-less stone", 2000).
