Roman mosaic with scene of Pankration

Roman mosaic with scene of Pankration (total combat sport, a mixture of wrestling and boxing with minimum rules) in the gym, on the sand, dated to 200-220 AD.
The two mature athletes, with powerful and vigorous physique, probably carry out the combat training phase while standing, the one we nowadays refer to as the term sparring, using striking techniques (the use of percussion, such as punches).
The mosaic was found in Salzburg (ancient Iuvavum), in Austria, when the Mozart monument was erected (in modern Mozartplatz). The series of mosaics that formed the floor bore the Latin inscription "hic habitat felicitas, nihil intret mali", "happiness lives here, nothing that is bad enters it", now visible at the Salzburg Museum.
