Origin • Gift of Athena • Symbol of Attica/Athens • Never most important Attic crop and likely not primary export
Production and Uses Production – growing -crushing -pressing -transporting Uses - -light -cooking -bodies -ritual
Production • Growing: • Lower slopes of Apennines • Spain • Southern Gaul • Greece • Asiatic provinces • coastal Tripolitania and Cyrenaica • African provinces
Production • Growing • Highly drought-resistant • Sensitive to frost • Usually crop every other year • Cuttings, ovules and grafts • Olives do not grow true to type from seeds • Table/oil varieties • Rarely mono-cultured
Production • Growing • Combined with pastoralism • Harvested in autumn/winter • Greeks and Romans liked “white” olives for oil
Production • Crushing • Packed in salt/saltwater first • Not edible raw • Crush first • Many devices known • Simplest – flat bed and stone roller, pestle, wooden sandals • Best is Roman trapetum
Production • Crushing • Don’t crush stones – add bitter taste • Luxury/quality oil removed stones first or minimal crushing of stones • Machines existed for stone removal, questionable effectiveness • Crushed olives moved to frails, then to presses
Production • Pressing • Simplest and most common press = beam • Weighted with rocks, human pulling • End fixed in wall as fulcrum • Weight pulled onto crushed olives in frails, pressing oil out
Production • Pressing -Improvements to beam press incl. winch, lever and drum, better anchoring -Screw 1st assisted, then replaced beam -Direct screw press replaced beam 1st C. CE -Possible because of screw, screw nut 3rd C BCE --Pliny, screw extracts more, risks bitterness
Production • Pressing • Separate oil and water • Romans ladle from top per Cato (Agr. 66) and Columella (Rust. 12.52-8-12) • Greeks more commonly use bottom spout method • Presscake remains, used for pig food and fertilizer
Production • Transporting • Most olives raised and consumed locally • Oil keeps better, and is traded • Luxury oils for quality, taste, added flavorings traded like vintage wine
Production • Transporting • Attica, Samos, Venafrum, Baetica, Cyrenaica all famous for oil • Stored and transported in large jars (dolia/pithoi) • Sold in amphorae • 2/3 sherds in Mt. Testaccio are olive oil amphorae • Peak in trade 140-165 CE
Uses • Light • Lamps were pottery, bronze, gold, silver, iron, lead, ceramic • Single or multiple nozzle styles • Freestanding or suspended • Smokeless or minimal smoke
