The Sanctuary of Apollo: a stratified monumental context and its materials

From the late 1st century BC to the first half of the 3rd century AD the Sanctuary of Apollo at Hierapolis saw a succession of various building projects. The recent architectural studies of the temples and porticoes and the archaeometric analyses provided an opportunity to study, in a diachronic perspective, the stone procurement strategies for these various building programmes. The use of freshly carved local marbles, the role of the Marmar Tepe and Thiounta quarries and the hypothetical existence of a number of separate work lots in the Augustan and Julio-Claudian period are discussed. For the 2nd and 3rd century phases, new trends, such as the use of coloured and imported column shafts and the increasing importance of the re-use of older blocks, are highlighted.
