From the island of Paros came lychnites, a Greek marble used mainly for statuary that was quarried in tunnels by torchlight.

The unformed blocks, destined for sculpture, still have cavities for lead seals and various inscriptions that make it possible to date them precisely; some of the latter include the name of Hermolaos, the individual in charge of quarrying operations, also carved onto the quarry walls on Paros.

By contrast, the half-finished bases (F-I) and Ionic capital (Q) of a late period are in Thasian marble from the Aliki district, whilst the parallelepiped block comes from the area of Cape Vathy.
