a Palladium is "a statue of Pallas whose preservation was believed to
ensure the safety of Troy"

Or, perhaps, the preservation of Edgar Allen Poe? "...the pallid bust of Pallas..." in The Raven. There was also an Italian architect, Palladio, in whose honour the Welsh composer Karl Jenkins wrote the eponymous musical work which has recently been used by the deBeers Company in their diamond commercials.
