- A marble slab roughly triangular in shape carved in relief with
the upper body of a man looking to his left and with his arms outstretched.
The slab is broken across the left forearm.
- The slab is 2.09 m long, 62 cm high in the centre, and the height
of the side that is still complete is 26.15 cm. It is approximately
10 cm thick.
- The marble has been analysed and is neither from Athens nor Paros
(two major sources of white marble). It may have been quarried in
modern Turkey or another Greek island.
- Until 1988, the Oxford piece was the only known metrological relief.
Then another example was discovered on Salamis, near Athens.
