Lamassu facsimiles created for the exhibition Nineveh at the Rijksmuseum van Oudheden

Factum Arte and the Factum Foundation recorded and produced the facsimiles of a pair of lamassu, Assyrian statues of winged lions. The statues were recorded in 2005 at the British Museum and the facsimiles were produced in 2014 as a donation to the University of Mosul and in 2017 for the exhibition Nineveh at the Rijksmuseum van Oudheden.


In 2005, Factum Arte recorded with non-contact technologies two Nimrud lamassu in the collection of the British Museum. As part of the documentation process, the colours of the lamassu were compared with specially-made colour swatches, which served as a reference of their exact colour. The high-resolution information obtained after scanning these winged lions was processed and prepared for routing.

The information recorded from the lamasu was routed in sections in a high-density polyurethane. These sections were assembled to create a prototype and verify the overall fit.

Each part was covered with numerous layers of silicone and a supporting fibreglass jacket to create a mould. These silicone moulds were used in 2014 and in 2017 to create the facsimiles.

The facsimiles of the lamassu replicate the exact colour and texture of the original. Factum Arte´s Sebastian Beyró carried out multiple tests at the British Museum comparing the colour and texture of stucco marble samples with the original. From these samples and tests, he created a specific recipe to ensure the accuracy of the replica.

The facsimiles were made in stucco marble and coated with wax to obtain its distinctive colour.
