The use of colouring on the statue of Hierapolis

The paper presents the main results of the research into the ancient use of colouring on marble statues in Hierapolis, which integrates the art-historical approach and the archaeometric investigations. the items discussed in the paper are the reliefs and decorative statuary of the Severan theatre, and materials from the north agora. Egyptian blue, red and yellow ochre were detected, together with traces of ancient treatments. Some new data on the ancient restorations of the statues of the larger-than-life statues of Demeter and Kore-Persephone, which underwent an interesting "updating" process, are also presented.
