Today, at a ceremony attended by Bundesamt für Kultur BAK, Federal Councillor Elisabeth Baume-Schneider, head of Switzeland's Federal Department of Home Affairs (FDHA), handed over this exceptionally well-preserved 2nd century BCE gilded funerary mask to the Egyptian ambassador to Switzerland, Mohamed Yehia Mohamed Negm followingthe Swiss Court's ruling that it be returned to Egypt

The mask gained the attention of The Federal Office of Customs and Border Security (FOCB) in Switzerland on 15 September 2022, when a transporter presented paperwork for importation at the customs checkpoint in Bardonnex (GE) on the motorway between France and Switzerland.  Customs Officers, suspicious of the artefact's provenance, blocked the Egyptian object's import while checks could be made. 

A subsequent examination by an expert with the British Museum concluded that mask was authentic and dated to the middle of the Ptolemaic period, a period that extends from 323 BCE (death of Alexander the Great) to 30 BCE (suicide of Cleopatra VII and Roman conquest by Emperor Augustus).  The expert also believed the mask likely originated from a cemetery located in the south-eastern Fayoum region, about 100km to the south of Cairo, which has been subject to looting. Investigators placed particular weight on the fact that an object of such exceptional quality but which is previously unknown to the scholarly community, is something considered unlikely had the artefact come from a documented archaeological excavation. 

Geneva prosecutors, in turn opened a criminal investigation in September 2023 for receiving stolen property and possible violations of Switzerland's Federal Act on the International Transfer of Cultural Property.  By order dated 6 February 2026, the Public Prosecutor's Office ordered the mask's confiscation.

What makes the case particularly interesting is the object's circulation.  According to Tribune de Genève, Geneva collector Stéphane Barbier-Mueller had purchased the mask from Samuel Merrin of the Merrin Gallery in New York, reportedly to decorate his home.  Proceedings involving Merrin were ultimately dismissed, and Barbier-Mueller, who waived his right to contest the Egyptian object's confiscation, was not prosecuted.   

It does, however, place another antiquity handled through the Merrin orbit among a growing constellation of objects whose provenance has subsequently collapsed under enforcement scrutiny.

This is far from the first such example. One of the earliest and most striking was the so-called Merrin Zeus, a small bronze statue stolen from Rome's Museo Nazionale Romano in 1980.  By 1984 the bronze was recorded as the property of Edward H. Merrin in New York, accompanied by a collecting history claiming that it had come from a Swiss collection dating back to the late 1960s.  That chronology was impossible if the sculpture had still been in the Roman museum until 1980.  

The pattern has continued at a brisk pace even this year.  In April 2026, the Manhattan District Attorney returned the Block Statue of Ankhwennefer, dating to approximately 690–650 BCE, to Egypt. Prosecutors state that the statue had been smuggled from Egypt during the late 1980s, brought into New York by Ed Merrin, and subsequently sold to the Metropolitan Museum of Art in 1993. 

And in July 2026, two more Merrin-linked antiquities were returned to Mexico. A Nayarit Standing Male Figure, dating to approximately 100–400 CE, had been sold by the Merrin Gallery before eventually entering the Metropolitan Museum of Art. A Xochipala stone bowl, dating to approximately 1200–900 BCE, first appeared at Merrin Gallery before prosecutors seized it in December 2025.  Both were repatriated by the Manhattan District Attorney's Office. 

The Swiss mask therefore should not be viewed simply as an isolated customs interception. It sits within a much longer record of antiquities that passed through the Merrin Gallery or convicted members of the Merrin family before later being identified as stolen, illicitly excavated, illegally exported, and subject to repatriation. None of that, by itself, establishes criminal knowledge in the present Swiss case, which was closed without such a finding, but it does, however, reinforce a central lesson of the antiquities trade: a dealer's reputation, an established gallery address, or an object's passage through major collections cannot substitute for a verifiable and documented archaeological and ownership history. 

Provenance must be demonstrated, not presumed.
