Left end of the sarcophagus of Sosia Herennia in the Museo Civico, Modena.
The fact that the architectural framework and inscription on this sarcophagus have been carved but all the spaces for figurative scenes left roughly worked would seem to indicate a division of labour between multiple carvers with different specialists. Alternatively, if one carver worked on the whole project then they were keen to split their work into defined forms: architecture, inscriptions, figures. On an object this large it is possible that a team of carvers worked on it together, perhaps as many as four.
