Christoph Schwall and Tatjana M. Gluhak Abstract: This study is based on the assemblage of grinding stones from the Greek colony of Selinunte in Sicily. Most were brought to light in well stratified contexts dating to the 6th century BC making them ideal subjects for research on the development of early milling techniques. In addition to saddle querns, Selinunte has Olynthus mills and mills driven by rotary motion were discovered in previous excavations that are also representative of advances in milling technology. The Selinunte assemblage can be compared to contemporary mills from elsewhere throughout the Mediterranean Basin. Based on these comparisons, we suggest a saddle type of mill model comprising of a boat-shaped upper stone and a roughly rectangular-shaped lower stone as a precursor of the Olynthus mill. The sources of the rock point to mainland Sicily, the Aeolian Islands and perhaps from the Aegean Islands bolstering the supposed importance of this coastal settlement as a centre of trade in the central Mediterranean.

Gluhak, Römisch-Germanisches Zentralmuseum Mainz, Ernst-Ludwig-Platz 2, 55116 Mainz, Germany; [email protected] Introduction oldest known circular rotary mills found in the western Mediterranean and dated to the 5th century This contribution focuses on the volcanic or possibly the end of the 6th century BC (Alonso rock grinding stones brought to light during the 1995; 1996; 1997; Alonso and Frankel 2017, 467- excavations conducted by the German Archaeological 72). The latter mills driven with a rotary motion Institute (DAI) at the Greek colony Selinunte on became common for grain milling during the Sicily. Close examination of these grinding stones Roman period throughout the entire Mediterranean provides an opportunity to present new data as well as in the Roman provinces (Runnels 1981, concerning the development of milling techniques, 128; Mangartz 2008, 192-94; Schaaff 2010, 268-69; as well as the opportunity to explore the systems of Wefers 2012a, 90-95). With regard to the occurrence rock procurement of a Greek colony in the central of these new milling techniques, the grinding stones Mediterranean. Sicily, in particular, offers important of Selinunte are of particular interest as they hail insights for the development of two different from well stratified 6th-century BC contexts and milling techniques. Firstly, in the 5th century BC, provide new data regarding the debate concerning the so-called ‘Olynthian’ or ‘Olynthus’ mill was the development of milling (Wefers 2011, 67-69; known throughout the eastern Mediterranean Basin 2012a, 87-90; 2012b). In addition, geochemical and and can be interpreted as an advanced grinding petrographical analyses of these artefacts allow us mechanism (Frankel 2003, 7; 2007, 222, fig. 15; to identify rock procurement systems and trading Alonso and Frankel 2017, 466-67).
