Detail of a tree.
On the Column of Trajan, Peter Rockwell has proposed that the trees - and many of the other background details - were carved by specialist landscape carvers. On the Great Trajanic Frieze there are many fewer background details and they are not given much attention, suggesting that some carvers were probably responsible for all elements of the design. In comparison to the trees on the Column of Trajan this one seems a little heavy and awkward and the leaves are much less carefully modelled.
