New data on the building site of the Theatre of Hierapolis

thanks to systematic sampling and pre-existing knowledge of the composition of the three orders of the theatre, the paper presents a detailed study of the criteria adopted for the procurement of marbles used in the construction of the scaenae frons. the building site of this monument has been the object of many studies, given its exceptional state of conservation, the dedicatory inscription mentioning the Dokimeian marble and the assumed involvement of aphrodisian craftsmen in the decoration process. the present research offers new data regarding (i) the first phase of the scaenae frons (augustan and Julio-Claudian era), (ii) the chronological development of the severan building site (early to late severan period), (iii) the provenance of the marbles used the logeion and the three orders (mainly from Marmar tepe and thiounta quarries), and (iv) the distribution of white and coloured marbles (both local and imported) aimed at emphasising the central section of the scaenae frons.
