Salvatore Aurigemma uncovered the Zliten mosaic in October 1913 within the ruins of a seaside Roman villa. He conducted full excavations between June 22 and the 18th of August 1914 to reveal the floor completely.
The Zliten mosaic resides at The Archaeological Museum of Tripoli where visitors see it near the entrance hall since 1952. It was originally found within the ruins of Villa Dar Buk Ammera near Leptis Magna on Libya's east coast.
Aurigemma proposed an approximate dating period for the Zliten mosaic in his 1926 publication placing it within the Flavian Dynasty years spanning 69 to 96 AD. Other scholars like Georges Ville and Christine Kondoleon have supported dates ranging from the end of the Flavian period to the early Antonine period or around 200 AD.
Portions of the Zliten mosaic are realized through a combination of three distinct techniques known as opus tessellatum, opus vermiculatum and opus sectile. The external black and white geometric border uses opus tessellatum while circular emblemata depicting marine creatures utilize opus vermiculatum.
The Zliten mosaic depicts animal hunts alongside scenes from everyday life including musical performances with a Roman tuba and hydraulis pipe organ played by a woman figure. Simplified floral forms and scale patterns link individual designs across different mosaics including the Reggio Emilia example.
