Although it was always agreed that the Parthenon Frieze fragment from Palermo  was being loaned to Greece for a limited period, it was always hoped that this loan might be extended, or in some way made semi-permanent. Unfortunately it appears that this was not the case however.
One positive side to this though is it weakens one of the arguments from the British Museum for rejecting the possibility of loans to the New Acropolis Museum – That they only loan items that they expect to be safely returned at the end of the loan period.
Hopefully Italy will see the benefits of returning the fragment permanently at some point in the future.

CULTURE: PARTHENON FRIEZE FRAGMENT RETURNS TO PALERMO
(ANSAmed) – PALERMO – A ship sailing from Naples has brought a fragment of the Parthenon’s frieze back from Athens where it has been on show since September 2008. The find had first been housed at the city’s old Museum of Archaeology, where it was visited by Italy’s President Giorgio Napolitano, before being transferred to the new Acropolis Museum. The art treasure, a piece of stone measuring 34 by 35 centimetres, is being kept in Palermo in a double strong box before being returned to the region’s ‘Antonino Salinas’ archaeological museum, where it has been an exhibit for over a century. The stone is a fragment of Phidias’ eastern frieze of the Parthenon and features a foot of Peitho, the Greek goddess of persuasion. The piece had been part of the collection of a British diplomat before it was donated by his widow to the University of Palermo in 1836; it then passed into the collection of Palermo’s National Museum when it was founded in the second half of the 19thcentury. The fragment will be on view when the Antonino Salinas Museum reopens. (ANSAmed).
