Short answers, pulled from the story.
The Zliten mosaic was discovered in October 1913 in the ruins of a seaside Roman villa near the town of Zliten in Libya, on the east coast of Leptis Magna. Italian archaeologist Salvatore Aurigemma led the excavation, which ran from the 22nd of June to the 18th of August 1914.
The Zliten mosaic depicts gladiatorial contests, animal hunts, and scenes from everyday life. It also includes circular panels showing marine creatures such as shrimp, murex, picarel, conger, sea urchin, and garfish, rendered in the opus vermiculatum technique.
The Zliten mosaic was created using three techniques: opus tessellatum for the outer geometric border, opus sectile for the central square panels each measuring 0.45 meters per side, and opus vermiculatum for the detailed circular emblems at the center of those panels.
The date of the Zliten mosaic is disputed and remains unresolved. Proposed dates range from the Flavian Dynasty years of 69-96 AD, suggested by Salvatore Aurigemma in 1926, to approximately 200 AD as proposed by David Parrish in 1985. Other scholars place it in the late 1st or early 2nd century or the Antonine period.
The Zliten mosaic is on display at the Archaeological Museum of Tripoli in Libya. It was restored and placed there in the 1920s, then moved with the museum to its new location in 1952, where it is displayed prominently near the entrance hall.
Salvatore Aurigemma, an Italian archaeologist, excavated the Zliten mosaic. In his 1926 work Mosaici di Zliten, he described the unknown designer as possessing an incredibly exquisite artistic temperament and wrote that one searches in vain for comparable life and spirit in other surviving ancient depictions of gladiatorial combat.
