It depicts a bound male prisoner being killed by a lioness. The upper torso and head of the prisoner are shown, with the giant lioness behind him, sinking her teeth into his skull.
The work is interpreted as a Roman sculpture imported to Scotland to serve as part of the tomb of a Roman military commander or dignitary, and connected to the nearby Cramond Roman Fort. The location of such a tomb, and how the sculpture reached its location in the river are unknown.
The sculpture is housed at the Museum of Scotland in Edinburgh. In 2003, plans were unveiled for the lioness to be housed in a new archaeological centre at the Roman Fort in Cramond, although this proposal was still at the initial planning stage in 2008.
