A painting by Marc Chagall showing the expulsion from Paradise, which hangs in Spock's quarters aboard the Enterprise-A in Star Trek VI: The Undiscovered Country as a reminder that all things end.
The painting appears in Star Trek VI: The Undiscovered Country, set in 2293. It hangs in Spock's dimly lit quarters aboard the Enterprise-A, a work of the twentieth-century Earth artist Marc Chagall depicting Adam and Eve driven out of the garden.
Before the ship leaves to escort Chancellor Gorkon, Spock's protégée Lieutenant Valeris visits him and asks about it. Spock explains that it shows a story from ancient Earth mythology and that he keeps it to remind him that all things end, a remark that covers both his own approaching retirement from Starfleet and the long hostility with the Klingons.
The exchange also frames what follows between teacher and pupil: he urges her to have faith that the universe will unfold as it should, while she is already part of the conspiracy to prevent the peace.
