altarpiece

noun

1. a work of art suspended above and behind an altar in a church

   “I walked across the concrete to examine the altarpiece of the atomic age. A large crack ran through it.”

   ““It’s this snaggletoothed, little bird-footed homunculus caricature,” Bourneuf said. “Many artists at this time were trying to make new altarpieces. Klee tended to take a very skeptical distance from the sort of grandiose projects of many of his expressionist peers, so I think it’s actually kind of mocking those hopes.””
