The quarries of Marmara Adası (ancient Prokonnesos) were an important source of white marble for sarcophagus production across the eastern Mediterranean and as far west as Rome. More
Roughed-out and hollowed-out sarcophagus chests and lids were produced on the island and then shipped overseas for finishing locally in a range of forms. On Prokonnesos itself a small necropolis was discovered containing various types of roughed-out sarcophagus. This necropolis seems to have served the small population of quarrymen on the island and perhaps some higher status traders and administrators.
