The walls of the building had marble revetments, from which fragments of slabs (chiefly at the base of the walls), mortar substrates (with or without traces of the slabs) and metal hooks for securing the slabs have survived. The hooks survive to a height of 2.5 meters from the floor. Study of the finds yielded a wealth of information about the techniques for setting the slabs and the design of the marble revetment.
The marble revetment slabs
The fragments of marble slabs found in situ show that for the wall revetment, white and colored marbles such as Karystian and Thessalian stone were used. The slabs did not have uniform dimensions and their thickness ranged between 1 and 3 centimeters.
The drawing of the marble revetment
The drawing of the marble revetment was done after the detailed recording of the hooks, the mortar substrate, the fragments of marble slabs, and their impressions, which were preserved mainly in the lower sections of the walls.
The drawing presents homogeneity and obeys a unified design in accordance with which slabs of different sizes formed successive horizontal zones.
