The Department of Justice is giving up its fight to reclaim for Egypt a 3,200-year-old mummy mask that disappeared from that country decades ago and later found its way into the collection of the St. Louis Art Museum.

“The Department of Justice will take no further legal action with respect to the mask of Ka-Nefer-Nefer,” U.S. Attorney Richard Callahan said in response to questions from the Post-Dispatch on Monday, the deadline for the Department of Justice if it wished to prolong the court battle.

Museum officials couldn’t be reached immediately for comment. According to court filings, both sides are still discussing payment of the museum’s legal fees.
