Notes

The grey granite from the Troad was a popular material for monolithic column shafts in the Roman imperial period and was used extensively all around the coasts of Asia Minor and in the Levant. The Yedi Tașlar quarries are one of the main sources of this stone and are famous for this series of monolithic shafts left abandoned in them. In this quarry the exact dimensions of the place where the columns were extracted from can be appreciated.
