The Greek prime minister has said the British Museum's decision to loan one of the Elgin Marbles to Russia is "an affront" to the Greek people.
Antonis Samaras added: "We Greeks are one with our history and civilisation, which cannot be broken up, loaned out, or conceded."
A depiction of the river god Ilissos will go on show in St Petersburg's State Hermitage Museum and will remain there until January.
