Marble bull's head from the temple of Eshmun

Excavations at the temple of Eshmun in Lebanon recovered a marble bull's head. It is now suggested that it was this head, apparently first published in 1967, that was placed on loan to New York's Metropolitan Museum of Art (Tom Mashberg, "Met Museum Turns Over Another Relic With Disputed Past to Prosecutors", New York Times August 1, 2017 ). The head is reported to have been handed over to the Manhattan district attorney after a request was received from the Lebanese authorities.

Sardinian warrior from "old Swiss collection"

One of the Sardinian bronzes of a warrior was seized from an as yet unnamed Manahattan gallery. It appears to be the one that passed through the Royal-Athena Gallery: Art of the Ancient World 23 (2012) no. 71. The collecting history for that warrior suggests that it was acquired in 1990 from a private collection in Geneva.

Other clues suggested that the warrior has resided in a New York private collection.

The identity of the private collection in Geneva will no doubt be telling.

The warrior also features in this news story: Jennifer Peltz, "Looted statues, pottery returned to Italy after probe in NYC", ABC News May 25 2017.

Mithras relief from Tor Cervara

A fragmentary relief of Mithras was discovered in 1964 at Tor Cervara on the outskirts of Rome. It was acquired by the Museo Nazionale Romano.

A further fragment of the relief was acquired by the Badisches Landesmueum in Kalrsruhe in 1976. The source was an unstated Swiss dealer. This fragment has been reunited with the rest of the relief [press release].

Today a further fragment of the relief was reunited with the other pieces. This had been recovered during a raid in Sardinia.
