Christie's has withdrawn for lots from its June 2020 auction after the objects had been identified by Professor Christos Tsirogiannis (Dalya Alberge, "Christie's withdraws 'looted' Greek and Roman treasures", The Guardian 14 June 2020). The four pieces are as follows:

• lot 25 a bronze Roman eagle identified from the Becchina archive
• lot 49 a Roman marble hare identified from the Becchina archive; acquired from "Tullio" in 1987.
• lot 113 an Attic black-figured Band cup identified from the Becchina archive. Reported to be in a private collection, Basel, and consigned to Galerie Günter Puhze, Freiburg; J.L. Theodor collection, Brussels; Sotheby's (New York) 17 December 1998, lot 77.
• lot 121 an Attic red-figured pelike attributed to the Washing painter identified from the Becchina archive. Surfaced: Sotheby's (London) 14–15 December 1981, lot 236. Then Dechter collection of Greek vases.

It would suggest that Christie's needs to tighten its due diligence process. Did the auction-house authenticate the histories of the lots before they were placed in the auction? Did it check with the Italian and Greek authorities before the sale?

I am grateful to Professor Tsiorgiannis for sharing this information with me.
