From Live Science:
A small bronze statue dating back nearly 2,000 years may be that of a female gladiator, a victorious one at that, suggests a new study.
If confirmed the statue would represent only the second depiction of a woman gladiator known to exist.
The gladiator statue shows a topless woman, wearing only a loincloth and a bandage around her left knee. Her hair is long, although neat, and in the air she raises what the researcher, Alfonso Manas of the University of Granada, believes is a sica, a short curved sword used by gladiators. The gesture she gives is a "salute to the people, to the crowd," Manas said, an action done by victorious gladiators at the end of a fight.
The female fighter is looking down at the ground, presumably at her fallen opponent.
It’s not known where the statue was originally found, though it is currently in the Museum für Kunst und Gewerbein Hamburg, Germany.
The rarity of such statues likely reflects the idea that female gladiators in ancient Rome were scarce. They were banned by Emperor Septimius Severus in A.D. 200 with only about a dozen references to them in ancient writing surviving to present day. The only other known depiction of them is a carved relief from the site of Halicarnassus (now in the British Museum) that shows two female gladiators fighting. There have been claims made in the past of burials of female gladiators being uncovered, but none has attracted widespread support among scholars.
