Damaged mosaic of Zeus —dating back 1,600 years — is now reconstructed. Take a look

In 1893, archaeologists discovered a massive mosaic among Roman ruins in Slovenia. Though it was well-preserved, a significant portion of the artwork was missing, leaving the viewer’s imagination to fill in the blanks.

But now, researchers have recreated the entire mosaic using a pioneering digital reconstruction technique, according to a study published on May 5 in the journal Applied Sciences.

Found lining the floor of a Roman villa in Ptuj — located near the Slovenia-Croatia border — the partial mosaic dates to the third or fourth centuries, making it at least 1,600 years old. When it was completed, it would have measured about 13 feet wide by 13 feet long.

It “is one of the most interesting and suggestive ancient monuments” unearthed in the region, researchers said.

In the central motif, it depicts a woman riding a bull, which is believed to represent the abduction of Europa, a well-known Roman myth, whereby Zeus disguises himself as a bull to seduce a Phoenician princess.

In the myth, after the princess climbs on Zeus’ back, he runs into the sea and brings her to the island of Crete. Their children then formed “a new Cretan dynasty.”

“The scene is connected to the myth of the colonization of the European continent,” and it would have displayed “the lifestyle, wealth, education, and values of the house master,” researchers said.

Upon its discovery, and on account of its high quality, the partial mosaic was transported to the Universalmuseum Joanneum in Austria, where it remains on display today.

Because of the symbolic importance of the mosaic, researchers set out to digitally reconstruct the entire work. In order to do so, they brought together experts from a variety of fields, including archaeology and graphic design.

The reconstruction process relied heavily on detecting patterns. Because the majority of the mosaic uses geometric patterns and “perfect symmetry,” the existing designs could be used to map out the missing pieces.

“Each step of the digital addition made it possible to think about the next step, both from the archaeological point of view to understand the meaning of each component of the mosaic, and from the point of view of graphic interventions and editing of the image information…” researchers said.

The reconstruction of the work sheds light on the creation of Roman architecture and enhances museum visitors’ experiences, researchers said. It may also serve as a prototype for a potential replica.
